My advice is stay broken up and just keep reiterating that the relationship isn't working for you and you have to take care of yourself first and foremost. I suspect that anything he's doing to "come around" is only temporary, set off by the fact that he probably expected you to be a sort of arm's length detached girlfriend for a long time. My fear if you took him back based on a few panicky moves on his part would be that he'd just go right back to the way he'd been all this time.
The bottom line is that it isn't as if you have seen this guy be emotionally available and then LOSE the availability. It has never, ever been there. So he's not suddenly going to just become a different person overnight.
Emotionally unavailable people stay that way because it works for them. They won't change if all the people around them accomodate them.
You know that I'm seeing a guy right now, and frankly he and I have discussed HIS "wall" or issues with emotional detachment...he's really good at being a friend, a very good friend, but as for that next level, he admits he's a "pull-back" hesitant to really let someone in type of guy.
My response to this? I'm pulling back from him. I'm not going to keep lavishing attention on him in hopes that my emotional availability will "change" him. He has to WANT to change. (He says he has a desire to open up but I don't think he knows how or he's scared). So like I said, I'm pulling back emotionally myself and just checking my feelings so that I'm not making any assumptions about he and I being any closer than we are right now. It's hard, but I don't see any other way to give him space to open up if he wants and to preserve my feelings too.
It may be that this guy could change, but not overnight and not just to temporarily appease you. I think your best course is to pull back and stick to your break up and GAL.
