FW told me not too long ago that sometimes he still feels like running. Not running TO anyone, just away. Sometimes he thinks about being away and getting to do stuff without any responsibilities and it was fun, but he realizes that we have fun too, but he also realizes that while a lot of it was fun, most of it was miserable. It's just hard sometimes to remember the miserable part when he's in the funk.
It's when he gets in his "funk" (that's what he calls it) that he feels this way.
It doesn't really sound like your H is spewing at YOU as much as he is just spewing and getting things off his chest. Hard not to take it personally. I do and I want to try to "fix" things when it happens. FW has gotten better at making sure I know that it's not directed at ME just at the situation in general and he realizes I'm not really to blame. Hopefully your H will get to this point soon.
