Who knows why anyone falls for another person? Sometimes it's so completely illogical that it's stupid.

And yes, he's hurting, and yes, it's because of you. But you know? Cutting ties would probably hurt him just as much, if not more. The way I see it is that you need to have a very long talk, a talk about what the both of you are looking for. And you need to have a smilar talk with Hitsugaya as well. And between the three of you, something needs to be worked out. I'm not sure what, because I'm really just a by-stander here with a few insights, but something.
