So I've been dating my girlfriend for four years now. We have a good relationship and from the way I understand it, we're in love. We live about 4 hours away from each other (college) so we get to see each other around two times a month, excluding breaks. Over this recent Thanksgiving break, my girlfriend spent the time at her grandparents house quite a ways away. We hardly got to see each other.
Now here is the problem. I've had this friend for about 7 years now. You guessed it... she's a girl. We used to be really close when we first met, (hang out, watch tv, go to the movies) childish things like that. We hung out very frequently for about the first 3 years of our friendship. We even made out a party once. She's always had a very huge obvious crush on me. I mean this girl would literally do anything for me.
For some reason we began to drift apart, and hang out less and less. I finally ended up getting the girlfriend I still have now, and the hanging out with my best friend was literally limited to once a month at the most. She also ended up getting a boyfriend.
So here we are today.
Over the Thanksgiving break, I for some reason texted her to see how she was doing. She was home from college and so was I. We hung out almost every night of break. Some alone, some with friends. She's single now. From the first night of break we hung out, I began to feel something for her. I don't know why because I've never felt like this about her. She's always been a friend. I wanted to hang out more and more with her. I learned she's got a new boyfriend now. She doesn't seem as flirtatious towards me as she used to be, probably because of that. I feel like perhaps I missed out on the chance that I had, and I might regret it.
I really do love my girlfriend, but I can't get my best friend out of my head. I don't know what to do, because I don't want to risk losing my four year relationship for something that might not even happen.
Please let me know what you guys think I should do. Also, sorry for any grammatical errors. This was typed very briefly.
