Sue - I would like to share some of what helped me early on in my sitch. The best thing that I did was set some boundaries regarding contact w/ow ho. No contact in the house, in front of me, etc... You and your daugther need a place that is a safe zone for you, where you know that you don't have do deal with H's crazy behavior. My home is my safe place and I protect it and fight for it to be that place of peace. It's up to you to define what you need to keep your sanity and demand that your H abide by those boundaries.
Secondly, we can all say confront, confront, contront and stop having sex with him but you need to do what you think is right in your sitch. Definately be safe! But, when you are ready, you will know that you are ready. It took me FOREVER to do those two things. Am I better for it now?? Yes! Did I have to wait until it felt right to me?? ABSOLUTELY!!
I guess all I'm saying is to take care of you and your daughter first and then go with your gut on the rest.
