He's 25, I'm 30. Can I trust him?

My neighbor recently has expressed an interest in some type of relationship. Obviously it's scary because he's my neighbor, I'm older, and if things don't work out, it's gonna be awkward. He seems sincere, however I have the feeling he doesn't want anything serious, although he says other wise. I've gone out with him twice. I have a good time, but I want a straight answer from him and he's not giving one. He'll say "what if I want something serious" or "don't assume I wanna get in your pants".

On the second date he took offense to me splitting the bill. I let him pay for the first date. Both dates have been for drinks, no dinner or anything.

Am I being paranoid or should I just let things take it's course?

I did leave out a part of the story. After he asked me out the first time, he called later that night at 3am, and asked me if I wanted to cuddle. I'm pretty sure he was drunk, and I politely told him no. He continued asking me to meet him in the hallway to talk. I again said no. Then he started talking about how he was "better, smarter, and more mature than the guys I have dated", and "I know you're not seeing anyone right now". Next day he explained he was drunk and didn't remember the call.
