I'm worried that my DH may be about to embark on an affair. 6 months ago he confessed to me that he was attracted to a woman he works with. I had been concerned about this woman as they share a love of football, support the same team and sometimes travel to away matches together. I have tried to be cool and supportive about them going to matches but it has made me feel jealous and threatened. I would never have wanted to forbid them going together as I felt he deserved trust and me to be grown-up about their friendship.
But 6 months ago, he went out for drinks after work, it ended up just the 2 of them and they admitted to each other that they were attracted to one another. He then came home and confessed to me, in a very drunken state, that they'd had this conversation but had agreed not to act on it. The day after this confession we went on holiday for 2 weeks and I watched him like a hawk - there was no text or email contact with her and he reassured me it was nothing, and nothing would come of it. So we moved on (though I was hurt and suspicious). But he is now changing. I feel he is much less affectionate with me, he is extremely critical of me and almost nags me about all the things I haven't done in the house. He has started going to the gym 3 times a week, taking more care over his appearance and trying to loose weight and just seems distant with me. I am away next week with the kids, he is alone in the house and I can almost sense that something is going to happen with her. I can't talk to him about my suspicions as he would be defensive, he called me 'pathetic' last time I mentioned I was worried about them. Does this sound like an affair waiting to happen?
