Caffe "...then kicked you out of your house and kept the kids..." Where does it say the OP wants to kick him out of the house?
LostGarden "I have often seen posts on various threads on MN claiming mnetters, on the whole, are prejudiced against men." What do you think 'prejudiced against men' means in this context? Do you think if the table was turned, genuinely, here that people would feel the male partner, main carer of kids, should be thorn out with his bags on the step and the locks changed because he started an affair and wanted to end his marriage? I don't think so.
Way more posters have laid into the OP and called her a lot of nasty things than have tried to be supportive.
She has met someone else, it's not a clandestine affair which has gone on for ages, hence the word in the her opening post recently.
There are men who have long term affairs, years, decades even. It is so well known that there is a name for the woman they have the affair with, a mistress. There is (to my knowledge) no male equivalent of a mistress.
In order to really understand what is going on with affairs I would want to know how many people have affairs and want their marriage to continue and how many have affairs and want their marriage to end.
For people in the OP's position, who (it seems) wants her marriage to end, then I think this puts the affair in a very different light.
Yes, it's still hurtful etc but it is more understandable, she is not expecting her husband to put up with her having a new man. She is expecting (it seems) for the marriage to end and her concern is for the kids.
