Some relationship consigli please

Okay so I met this boy at school a mese and a half ago, and we sort of clicked. We have the same taste in EVERYTHING. We started talking over Facebook and texts, and we started meeting up at recess, between classes, at his place o mine, we really have fun together. We disagree sometimes, we argue, but it's nice having a smart conversation with him. One time I apologized for something I had detto and he replied that I owed him a kiss, which sort of freaked me out.
I swore to myself I wouldn't fall in Amore this year, but I can feel myself falling deeper and deeper into him.
Two days fa I was at his place with a friend of mine, and we were really tired so we decided to nap. In bed, he played with my hair, held me while I slept, he was so sweet with me. We did cuscino fights and stuff, we played on the xbox, and he really seemed to like me. Even my friend detto so.
I still haven't dato him the baciare I owe him.
At new year's he's coming over, and since my sister's been bitching around about how I wished he was my boyfriend, he detto that we could prove to her that nothing was going on between us.
And that sort of hurt me.
I thought we had some sort of connection. Ok, he's four years older than I am, but he didn't seem to mind. Am I just another one of the girls he's playing around with?
