Maybe he has some mental issues, is he on meds? I know when i take my nighttime meds which are very strong and get me depressed at certain times of the day, I get very"out of it"emotionally , and say things i don't mean or i am just wishing for an escape from the situation I'm in, not that it is a bad relationship, but the depression comes on and I can't shut up about wanting to leave sometimes. It is a fleeting roller coster of emotions, too many at once. Your husband sounds like he needs to slow things down and not be so responsible for everyone else, maybe he is just going through the mid life crisis, you need to support him, and try to keep your feelings at bay for now, he may snap out of it, and if he doesn't he should see a doc and T if possible, where he can tell his feelings alone.
