Leave my husband or not?

Leave him! Don't listen to people who tell you to "work it out". Fuck that noise. Why try to make something work with a d-bag like that? You can go out and find a better model who won't make you question your relationship by talking to ex-girlfriends.

if you don't love him leaving him now is better than waiting until you're much older. it would be a lot harder with kids and if you're 35+. think of the financial burdens, the adjustment to the new dating scene and idea of telling your date about kids.

now is a good time to leave and start over, you're still young.

That's quite a toughie honey. None of us really can tell you to leave him or not. It's something you need to decide. Are you able to forgive him? If he is wanting to do that, it does suggest that he hasn't completely moved on. but really it's up to you. Think about it, are you going to regret leaving him? Can you find someone better given that none of us are perfect? Do you love him, or do you love what you want him to be, or thought of him to be? These are all questions you need to ask yourself, and things you need to take in consideration.
