here's how I feel about this person. I'm confused. what do ya's think?

I met him on plenty of fish dot com. We talked on the phone a few times and we met for the first time yesterday.
I think he's cute and nice and I'm really physically attracted to him. I just...he tried to hold my hand. And I wouldn't let him. So on the phone last night I asked him if he was looking for a fling and he said no. He's "actually really serious about me" and "really interested in me." I thought his answer was weird because we don't know each other. How can you be serious about someone you just met? He also repeated that in a row, like 5 times. Which I thought was odd too. It made me wonder if he was lying...I don't know I don't think he is lying I just...I like his personality, I'm really attracted to him, but something isn't *there* like...I just feel like he is so foreign to me. I don't want to date someone for the sake of just being with someone. It's just...I really want to...make out with him lol.

if anyone has any insight, wisdom, or advice, please say. thanks.
