Marc has spoken about his feelings for his girlfriend and Cerys in an exclusive interview for the ITV1 show and said he is “deeply sorry”.

He said: “I couldn’t say I don’t know what’s going to happen now that I’ve left. I was just about to settle down, eat a few beans and collect some more firewood a couple of hours ago and now everything’s up in the air. I don’t know if I’ll be missed in there or if I could have changed anything.”

On being evicted he said: “It all happened so quickly you’ve got a few minutes can’t even pack your stuff… off you go little wave. I had a cuddle with everyone before I left and people were upset. John asked me to pass a message to his family, Anna was in bits. I really felt for her.”

Of the whole experience he explained: “It’s tough in there, it’s not an easy thing to leave everything you know behind and set up camp in a jungle with strangers. It’s tough, it’s not just physically depleting, mentally you lose your fluidity - that would only be rectified when you had dinner in the evening.”

“My trouble, I think, was I just tried to put everything that I know and loved to one side just to try and live in the moment just try and be centered just try and live, basically, because we were living a very basic life there. I forgot about… you know I just came a bit self absorbed. You’re just in a little bubble and the only thing important is collecting firewood, de-startching the rice, washing clothes in the creek, washing yourself, getting along, having a laugh and everything else becomes secondary.”

He continued: “It’s really difficult to sum up my experience at the moment, I suppose I would say, you know, had this situation not blown I suppose I would have been saying just amazing I had an amazing time in there I really did. It was a great thing for me to do but you know the outcome doesn’t really… I have to weigh up the situation you know and I have to try and work out in my head what does this amazement mean what does it mean now? I don’t know.

“Now that I’ve come back to reality, you know, it’s my point of view has changed a little but a few days ago I would have said just amazing. Last couple of days have been really hard for me in there. It’s been a really difficult time and I’ve tried to make the best of it I could for me and I just had bouts where it was just up and down for me you know.

“I think the situation between Cerys and myself was getting… nothing happened between the two of us at all but it was just kind of getting to the situation where it was becoming more than just friends, you know, in our behaviour there was a lot of flirting going on and I realise as I was doing it but I couldn’t help it, but I just realised in the last couple of days that I shouldn’t be behaving like this I certainly shouldn’t be behaving like this.

“I felt like I was betraying my partner and I was you know. Not in the overtly physical sense but mentally you know.

“What I mean, I wasn’t with Sarah in there, I was just kind of in the jungle, I wasn’t with anyone, I was just kind of wrapped up in that situation. All I know she wasn’t there to meet me when I came out of the jungle, so that told me a lot and I know she’s now on the way to London. I spoke to her a little while ago she’s, well, she’s hurt. I’ve hurt her badly.

“I think I don’t know what time she left here but she’s somewhere I think she was at Kuala Lumpa airport so she must have just worked out the times and worked out what had happened.

“I don’t know, maybe someone texted her. I don’t know, we didn’t really talk about how she came to know that she could speak to me but I left a message on her mobile as soon as I got out the jungle.

“If I could have jumped on a flight to be with her straight away, that’s what I would have done but I’m only out a few hours and even if I left now there isn’t any chance of us linking up mid air.

“So we spoke, it was a personal conversation rather than anything about it was just about our feelings.

“Of course I did, of course I apologised, I can’t apologise enough. I mean I’ve had some texts from friends saying you know, you didn’t do anything wrong you just flirted. Chin up all that kind of thing but none of that matters when you’ve hurt someone does it? It’s not about how I’ve hurt or how little or how much I’ve done it’s just the fact I’ve brought tears to someone’s eye and for me that’s something I’ve always tried to avoid. I try and help people who are crying I don’t want to be the cause.

“No I didn’t plan to hurt anyone I’m absolutely devastated. I have …I didn’t plan for any of this to happen I literally want in to this jungle as a personal challenge, and I spoke to Dean Gaffney who did it last year and he said to me ‘you know Marc it could change your life this could be a life enhancing experience for you’ and that was what I was looking for. I know you could if the situation arises that could change your life in a positive way you’d be foolish not to take it. It still might change my life in a positive way but at the moment it’s not positive at all I’m devastated.”

Marc was asked what his relationship was with Cerys.

He said: “I don’t know, nothing was discussed about what the relationship was while we were in there we were just two mates having a good time, you know, we were just taking care of each other.

“I really saw the vulnerability in Cerys and she needed a bit of support, you know, when she was in there, because she’s quite a delicate little thing really. I think it just started off with me trying to be supportive for her and help her through this situation and we just had fun together.”

He was asked: “Did you want to discuss it?”

Marc replied: “I did, yeah I did, and I said to Cerys at one point I just can’t behave like this I shouldn’t be doing this because I did have someone on the outside that loves me and would be truly hurt by what she was seeing but I think by that time it was just too late, you know.

“We’d already, I mean, I say too late, we didn’t do anything. I didn’t do anything in there that I would class as cheating. I didn’t cheat anyone. I didn’t do anything like that but I have publicly flirted with another woman and had fun with another woman you know sometimes we would swing in a hammock and sing to each other and these are quite intimate things to do and at the time it was just a joy to be intimate with someone. I suppose I was just, you know, it can be lonely to be in a place like that.”

He added: “It’s really nice to sing with someone and just share time with someone so we’d always be off collecting wood together and looking at bugs and exploring the jungle, and I really appreciated having someone there like that that I could share that time with. I’m just sorry that someone’s been hurt in the process. I really am deeply sorry.

“I can’t say that Cerys is more than a friend at the moment, you know, we are just really good friends. None of us have any idea how we feel about one another apart from the fact that we really enjoyed spending time in each other’s company. That’s as far as it went.”

Marc was asked: “What’s going to happen with Cerys when she comes out will you see her as a friend or in a relationship?”

“I really hope so. I think it would be a real shame… you have an intense time with someone and then you can’t see them any more because you’ve been inappropriate. I’ve behaved in an inappropriate way. I suppose in my own naive head in my own naive little mind, I suppose I didn’t even think about the consequences of spending time with someone in there you know because there’s so little. I’d like to be able to support Cerys when… I mean she’s going to have to deal with this situation as well when she comes out, but on the other hand I’ve hurt someone that I’m in love with and that I’ve been with for two and a half years. We live together and I’ve just listened to her crying one the other end of the phone, so I haven’t got any choice but to do the right thing.

“Do you know what I mean? It’s not even about doing the right thing it’s just about decency and respect and I’ve been disrespectful enough.”

Marc added: “I’m glad that I’ve been voted out now because it would have been awful for me to put Sarah through a moment more despair than I already have.

“I’ve got no alternative but to get back to London. Things have to be discussed and resolved either way, so I owe it to her to face her, so I’ve got to put my own feelings to one side really. I regret hurting someone badly I really regret hurting someone. I really regret, I really regret that, but I don’t regret anything else,” he said.
