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

This isn't too long of a story, like the other ones I'm seeing on this subreddit, but I thought I'd try for some advice anyways! I am a sophomore in college, living in the freshman dorms as a transfer. I was dating a guy from home (about 2000 miles away) for about 7 months but we broke it off a few weeks ago due to the distance. However, I realized a few weeks before we broke up that I was developing feelings for my best guy friend here. We have so much fun together, and could hang out for hours talking about anything. I honestly think we'd be perfect together. Here's the catch--he has a girlfriend. They have been dating for a year and a half and she only lives 45 minutes away, so they see each other quite a bit.

My issue is if I should say something to him. Now that I am single, I am absolutely certain that I have feelings for him. Myself and my other friend think he has feelings for me too. But, I also know that he is devoted to his girlfriend. I don't want to be the "other woman", but it's killing me not knowing how he feels about all this. I have always been a confrontational person, hating the games that people play about love. I have always been the first in every relationship to tell them I like them, want to date them, love them, etc. I am just scared to talk to him about it.

On one hand, I want to know how he feels, so we can either proceed to work something out together, or I can try to get over it. Right now, I'm just in this weird place where I'm in love with my best friend, and I have no idea if our constant hanging out and flirting means something more than it is. I don't want to ruin the relationship he has with his girlfriend, because I've met her, and they do seem pretty happy together. I'm just lost. I've talked to one friend about it, and she said that even though she knows I want to talk to him about it, it will ruin our entire group's friendship dynamic, which is true.
