Dominic West believes his marriage has given him "freedom."
The 46-year-old actor married his wife Catherine Fitzgerald, with whom he has four children Dora, Senan, Francis and Rose, five years ago but has admitted they are still just as strong as they were when they first tied the knot.
He explained: "I fell in love with my wife when I was at university and I managed to persuade her to fall in love with me for three months but then she ran away and married someone else.
"But I've been in love with her since then and still am, even more so ... I think I have a really good marriage, mainly because my wife is so cool and I adore her and we have all these kids.
"The mistake people might make, if I may be so bold, is expecting so much of a marriage and hoping that there can be perfection.
"I think, really, what marriage is, is two people helping each other to live the best lives they can. And that's what happened with me and my missus. That's why it works. She doesn't get jealous, either."
And, despite Dominic, who has daughter Martha from a past relationship, having a highly successful career under his belt, he believes it is "essential" Catherine has her own job and that's why he's so proud of her eight-year restoration project at Hillsborough Castle in Northern Ireland.
He told Britain's Vogue magazine: "She would go pretty mad pretty quickly otherwise. It's a big public garden, so she's very busy doing that and she loves it. It's the only thing keeping her on the straight and narrow."
