"And, when he screws up, he blames it on everyone else. "

I would suggest to try to see what everyone around him normally does when he screws up. Is it all different? the same? what are his reactions to those people and is it different? Why not doing a 180 the next time he screws up and see what happens.

"But, in reality, I think H reacts to his own issues, most of which have nothing to do with me. I just end up getting the brunt of it because I'm an easy target for him."

YES, this is totally right, IMHO. Just try as hard as you can not to let his comments/actions affect you. the outcome will be better. there have been several times where your H was being rude or whatever, and you chose to keep happy and you turned his mood around. You've written this several times, so just keep doing it, it works. ;\)
