Why do you still want him around? Are you willing to take him back in a yar knowing he left the door open for both of you? I am asking I do not know what I would do. As for your kids how old are they? I do not know if you can or can not do this, but I would talk to him about the kids never finding out about this affair. If you 2 get back together this could hurt things especially daughters. Legal seperation is all. Make sure he can not start accumulating debt and make sure you are getting support for kids and your home $$$. Seperate finances so later on you are not stuck w/his responsiility. That other woman is something else. Sorry for your pain. Take care of yourself and your kids. You seem pretty level headed good luck and keep posted!!!
