Fathersyros "Husband should chuck her stuff in carrier bags and change the locks." He might try it but it would be illegal and anyway, what would that solve. She can ask the police to let her back into her home.
SherlockStones "Based on fuck all except the fact he possesses a penis, why oh why am I not surprised"
This has nothing to do with having a penis, and everything to do with what has been said.
People have been quick to assume the unhappy marriage and mental health problems are all of the *OP8's making. I do not see that as so. I find it hard to imagine many people, male or female, signed off work with stress because their partner had an affair unless there were existing mental health issues.
I've had mental health issues, about one in three people have them, it could be something mild or major. From what I've read it sounds like it may have played a part in the unhappy marriage.
The OP had an affair a while ago but they "Tried to mend everything for sake of kids. Didn't work, both very unhappy ..." This does not sound like a woman out living the high life. She stuck with the unhappy marriage for the sake of the kids. So, presumably, did he.
If she had met a new man and was living the high life with him would she be coming back and caring for the kids if she did not really want to care for them? My thoughts say no, she would be long gone. So she does care for them, she has fashioned her working life around being the main carer.
And yet, despite the fact she loves the kids, does not want to lose her main carer role and is doing all she can to look after them through this difficult time, she is willing to leave to help her husband accept that their marriage is over. Yes, a time she has made difficult, but none the less it does not sound like she was caught out, it sounds like she came clean and told her dh.
In spite of her love for the kids she is asking us (MN) whether she should just leave them to make it better for her dh.
Does that really sound like a heartless bitch out for herself?
Not to me. It sounds like an unhappy women, in an unhappy marriage, crippled by guilt because she had an affair years ago, tried to make her marriage work for the sake of others and now has met someone who makes her happy.
Affairs are horrible indeed, but this sounds less like 'I got caught out' and much more like 'I am leaving you for someone else', which she is perfectly entitled to do under British law!
