I let it out from time to time and it does make me feel better to let H know what I'm feeling and thinking. I don't think it makes any real difference to him what I do lately. He's just off in his own head, sticking to his IDLYA as the bottom-line explanation for this, that it's not something he can change, etc. He is being a good dad anyway and wants to do what's best for me and the kids--as long as it involves marital separation.
I say let it out once in a while. It's just too hard to rise above this crap all the time.
