Falling for Your Best Friend

Falling for your best friend could probably be one of the worst things to do. More so like a curse or a blessing. I have this one friend I've always had a crush on since senior year of high school... but at the time I was in a relationship so it would have never worked. Now we are in college and attend the same school. We're both single so I'm like this is the perfect opportunity to try to see if something is there. In the beginning of first semester we pretty much hung out all the time whenever we could pretty much. He was that one guy friend I could be myself around, joke with, and etc so it was perfect. It was then I realized that I still have feelings for him. However, I did not know how to bring it up or if I should even do that. Well one day I decided to ask the question. I guess you could say I got the answer I wanted to hear but you never know with guys... especially when they say "but I don't want to ruin the friendship". So you are just sitting here like wtf.. well weeks go by and I find out (being nosey) that he has a girlfriend. I had so many different emotions but my main emotion was to beat his ass. That was because even though I had feelings for you, I was your friend you could've at least given me that common courtesy. Was I hurt? Yes, of course. But I couldn't show that emotion especially if they had that I don't care mentality. Till this day I still have feelings for him. Why? I honestly don't know. My main problem is that I see the good in people. I know that he is a good person and he is a good friend but he chose to make a decision and that decision affected me. I should be over him but I'm not and it truly sucks fucking ass.
