Once trust is broken, that's it. My daughter, 3 years ago now, rang me (I already knew there was something wrong) and I told her to look in his pockets. Sure enough,, hotel bills etc., etc.. It was horrible and I know how you must be feeling. I couldn't believe what he was doing to his children. (9 & 7)
We are still working at them. I am now down to plain angry. I don't know how I can help, but if you can think of some way then I am there for you. It's hard, we're surviving. You will all survive - but it is so very sad.
