<human>: Quick history: I had my first boyfriend the summer before college (so 1.5 years ago). We stayed together going into school (long-distance), but around Thanksgiving our relationship was failing and I started crushing on my best guy friend. I broke up with my boyfriend (on good terms) and my best guy friend and I started hooking up. We dated for a little bit (i.e. last February) but it ended very poorly - he ended up lying and causing me a lot of emotional stress/pain. Now we don't speak, because I don't really want speak to him because I felt he betrayed me as a friend, basically.

Since then, I've been single except for dating someone for a month in October. But recently, I think I've been crushing on my (new) best guy friend (I often have just as many male friends as female friends), and I'm pretty sure he likes me, too. And while I'm usually a big advocate for going for a relationship if you like someone, I'm really wishing I didn't have a crush on him, for a few reasons:
*the current situation very closely mirrors where I was a year ago the first time around, and while the guys are very different (at the time my friends told me that he was a jerk but I didn't listen) I'm nervous that things could end badly (again) and I could lose a close friend (again)
*he's in my close group of friends, and I'm nervous us dating (and potentially breaking up) could complicate that
*I'm not sure if my feelings are genuine, or if I'm just emotionally rebounding to the guy I'm closest to emotionally (like I did last year)

That's basically it. I think this is one of those scenarios I should be 100% sure of before taking action to prevent emotional harm to him or complicating our friend group.

Summarize the given text in a few sentences.
<bot>: I think I'm falling for my best guy friend, which worries me since I did that a year ago (with a different guy) and it ended poorly
