Wtf is up with me

OK, so, I don't usually talk about my problems on here. In fact, this is the first time. So here goes.

First, let me start by saying, I don't get attached. It's hard for me to get attached to anybody or anything. I've never had a boyfriend that I got clingy with or never lost interest in within a few weeks maybe months.

Until now.

It's like a switch was clicked in my brain and now I'm super attached to this guy. He's not even my boyfriend and we haven't even known each other for very long actually... But I am totally freaking on the inside about my attention to him. I've told him about how sexy I find him and how much I like his scent. We've had sex a few times as well and (tmi alert) he's pretty good at pushing all my buttons and driving me crazy.

I think I'm going crazy. I'm becoming one of the girls I used to joke about falling over if they didn't have their man's arm to hold on to lol. Btw I'm 19 and he's 24.
