My H has big guilt issues to, and I think this has caused him to want to leave, and then come back, because he says he feels like he doesn't deserve to be with us, or have a second chance. Its hard to live with this though, and I totally understand your being tired! I think we should all get together on an island somewhere for a break!!!
But take care, and continue with the retro stuff, it does help!
