i agree...it does seem odd that he wouldn't take things slower and be more informed about how to approach domestic violence victims specifically.
He could indeed be in love, and that could be a rare thing for him. That said, he could also have some kind of personality disorder. If he's not really hearing you and fixated on some idealistic version of the relationship, he's lost in his own projections. That's kinda immature to begin with.
It is POSSIBLE that he does make a habit of preying on fragile people, whether conscious or not. He could have a savior complex.
As for you not being in love, that's a very personal thing. I struggle with that as well because I have perfectly good guys ask me out but I don't feel anything, and then when someone really complicated and beautiful comes along, that tends to feel like love (but is detrimental and flares my trauma responses big time).
I'm getting to the point where I want to be with someone who's intelligent, stable, a good listener, empathetic, strong, loving and generally happy on his own. I no longer want to play with fire, interacting with others who also have major traumas.
I think that love can grow sometimes, but you can't force it if he really doesn't light you up at all...
