TX Girl, you have to do what is best for you. I'm not saying that you should not do what is best for your daughter it is just you have to be OK yourself in order to be there for your daughter. If you and your husband cant work this out, than you need to prime your daughter for the inevitable, she will heal. Many people divorce and the children end up fine. Living with your estranged husband does not sound healthy for anyone involved. I wish you the best of luck!
