<human>: Summarize the given text in a few sentences.

A few months ago, a new guy, Harry, moved to town. He has a medium distance girlfriend who he sees just about every weekend. They used to live together in Guatemala, where they met and dated for about 3 years before coming home... They seemed to have a pretty good relationship, but since he moved here it seems to have been deteriorating. I've seen him go from eagerly looking forward to seeing her and excited about the idea of just talking to her, to ambivalent, to resentful. She is a lovely, lovely girl. She is really sweet and gentle and caring. But. I don't think they're a good match at all cos he has such a wicked sense of humour that just zooms straight over her head. 

Meanwhile, I started out thinking he was just a really cool guy - he and I are pretty similar, we share a sense of humour and tend to enjoy the same things. I was really excited to have a guy who I could just have a decent chat with. 

Here's the thing: Drunk S_I_M_P and drunk George get a little too close sometimes. Nothing that could be considered cheating... just flirty and handsy. He has given me some indication that if it weren't for his girlfriend he wouldn't stop what starts when we have a few drinks...

Now the bit I need to get off my chest: I noticed a couple of days ago that I actually have feelings for him. Big feelings. I already love him as a friend, but I recently realized that it's not at all as platonic as I thought :/  I was looking over at him just derping around, and something about him seemed to shine and I had an epiphany that I actually really want him.. I can not tell anybody about this. 

FUCK I don't wanna be a homewrecker. Why is he in a relationship? I'm not usually attracted to unavailable guys, so I'm really fucking mad at myself for developing feelz for a guy that is totally off limits. How to stop? WTF BRAIN/HEART this is so not cool.
<bot>: Just realized I have the feels for a guy in a relationship. Want to go there, simultaneously hate myself for it.
