<human>: I [22M] have been dating my boyfriend [22M] for about 6 months. I hung out with him and his best friend [21M] for the first time ever the other day. His best friend is totally awesome and him and I have so much in common. I messaged him and told him to let us know when he's available to hang out again. 

He messaged me yesterday (Sunday night) and told me he was free, but my boyfriend didn't want to go. So, I hung out with my boyfriends best friend alone for about 4 hours. We walked, talked, and caught Pokemon. I found myself enjoying every second of the conversation and he's such a nerd about stuff which is totally adorable. He even said, "I'm starting to like you more than him..." meaning my boyfriend and they've been friends since they were kids. I just have a lot of mixed feelings going on right now and I don't know what to do. My boyfriends friend isn't gay, but he's curious and never dated girls. 

That being said, I've never cheated and I never will. If I know I'm starting to like my boyfriends best friend more and more, is it cheating to continue to hang out with him??
