Kym Marsh wants a divorce from Jamie Lomas amid allegations she has cheated on him.
The 'Coronation Street' beauty, who reportedly had a fling with her former co-star Oliver Mellor, has decided the couple's one-year marriage is over and is said to have pinned the blame on the 'EastEnders' actor's "unreasonable behaviour", despite speculation she has been unfaithful to him.
The 37-year-old stunner is said to have told a friend: "I've had enough. I want a divorce.
"Jamie's behaviour has been erratic, at best, for some time now. This is the only option."
Kym - who plays Michelle Connor in the ITV soap - clashed with Jamie a few weeks ago which led to her calling the police when he reportedly flew into an alcohol-fuelled rage.
Her friend told the Daily Mirror newspaper: "I think Kym has known for a long time, in her hearts of hearts, that things weren't going to work out.
"The bust-up at their house a few weeks ago was the final straw. It left Kym ¬frightened for her safety. She can't live like that."
The brunette star is alleged to have had a five-month affair with Oliver, who played Dr. Matt Carter in 'Corrie', just five months after she tied the knot with Jamie, but she is said to have tried to make their marriage work for the sake of their two-year-old daughter Poppy.
Her pal added: "She desperately tried to make the marriage work for the sake of their daughter but it's become obvious that things can't continue.
"Kym's only focus now is her children. To say she is devastated is an understatement. Anyone who knows Kym can't believe she would have an affair."
After finding out about the cheating allegations Jamie took to his Twitter account to demand a showdown with Oliver.
In a message to the actor, which has now been deleted, he wrote: "You need to come and see me."
Jamie - who plays Jake Stone in 'EastEnders' - is also said to have phoned 'Corrie' producers and cast members in the early hours of Saturday morning (12.10.13) in an attempt to get Olivier's phone number.
