Trust me, we all go through those periods where we feel we can't go on. I often think that if I was not here my W would have to deal with the real world for a change and not the fantasy one she has built for herself. You must detach! Simple as that. Not necessarilly physically but emoytionally. I found GAL to be my lifejacket. I could still feel good about me. Find things to do that give that to you. Learn something new. If you need a weekend away tell your W you are doing so, she doesn't have to know why. BUT, remember if you leave for any period of time without a Separation agreement in place you are leaving yourself open to problems re: custody. I know you don't believe your W would ever do anything to endanger access etc. but did you ever believe she would be unfaithful? Cover your a** as you take care of you. Wow, and your MIL thrown in to! Sounds painful. P.S. Remember the waves, they come and they go. Our emotions are like that too. Hang in, guy!
