Mish, it sounds like he was actually upset that you DIDN'T ask him for help? So maybe you are underestimating his desire to be more of a partner to you than you think he is capable of.
In your old R, he said you asked for too much. Well, this is a new R. And besides, when a spouse leaves, we have read so many various reasons/rationales they give, it doesn't mean any of them are true. I mean, come on. My ex says I wasn't supportive of his dreams and yet I moved 9 times in 11 years for his job?? Just because he said he didn't want you needing him then, doesn't mean he isn't capable, and desiring, to be helpful now...
