Will he eventually be over his ex?

I've been kind of hanging out with this guy-it's very new we've only been talking for about a month-and I noticed he was acting distant, so I asked him about it, and he dodged the question, saying he'd explain one of these days. we were talking online a few days ago and I brought it up again, and he told me straight up that he's not over his ex; he gave me full details, how he had messed up with her and she ended it and now he's mourning the loss. they've been apart for at least a year now, and they're not in touch; as far as he (and i) know she's totally over him. but I'm friends with her from my place of work..she's beautiful, tall, skinny, and so sweet. I'm short and skinny, pretty enough (a lot of people have told me they think I'm stunning but w/e!) so I'm very upset. on the flip side, he wouldn't have been so straightforward with someone he didn't trust; he said he'd never told anyone that before, and he told me he likes me a lot,enjoys my company, etc. he said he's open to the possibility of someone else for him but it would take a long time. I haven't slept with him and not planning on it anytime soon; we just cuddle and make out..and I asked him to ihs face if he'd rather just be friends or nothing, to which he shook his head no and said he wants to just take it as is; but how can I deal with this? he's a really good guy. and he doesn't owe me any explanations, but he gave it anyway. and he did tell me that I "turned him on more than he has been in a VERY long time." he told me he's dead on the inside, but then looked into my eyes and said "maybe not completely dead" and kissed me again. I am so baffled. do you think he could develop those feelings for me instead?!
