Past behaviors are a good prediction for future behaviors. What coppertop said is right, the sooner, the better. And it will make you happier in the long run knowing you won't be used.

i dont like her

Get rid of her before she completely sucks you into her miserable abyss. And take the kid.]

Save yourself a world of grief.

I am truly sorry to hear. If I were a man and were in your shoes, I would definitely leave. I know it's easier said than done, but there is no way on earth you should be with a person that sleeps around on you. She is your wife, not your girlfriend and you deserve respect. Maybe the whole marriage and motherhood thing isn't for her and she is still immature in a way, but you shouldn't suffer due to her lack of self respect. I am sorry that you have to deal with this but the best thing would be to move on and find someone who will respect you. Trust is one of the main factor in a relationship and if it isn't there, then there is always that doubt, and that doubt can drive a person mad. I understand that you are trying to get her help, but people like her doesn't change, 5, 10, 15, years from now, she will become comfortable again and will do it all over again. Please be strong and make the right decision here.

Let another fellow attorney weigh in on this, although I pretty much echo earlier advice. First, there is the legal side of things, and in the interests of your child you have no choice but to file asap. I'd do that at the same time as telling her that I am seeking custody...if you stress the importance of your desire that she needs to continue to be involved as a parent, there's a good chance that she'll go along with that (she has no responibility, and little guilt, if you present it correctly...she obviously doesn't want the responsibilty of primary custody). Part two is for you to get counselling, to get her behind you, and to begin looking for someone who is a match. You and she are obviously in way different places...that's the reality of it, and wishful thinking won't change it. Good luck.
