Just like Nanc. said. I'm sorry your guy is being such a jerk. Mine has had his moments as well. I think sometimes they fall into "selfish" mode and they don't "get it" until something snaps them out of it.
As if being in so much pain isn't hard enough to push yourself through, then the emotional pain just makes it that much harder.
I hope he comes to understand and appologizes. Have you been to RSDHope.org? There's some really good information on the site to help family and friends try to understand.
Hang in there.
