So I love my girlfriend, but she seems to be making me less happy everytime I see her. We've been together for almost 2 years now, but all i can think about is another girl who i liked before this one. I've had feelings for this girl for the last 3 to 4 years but one of us has always been in a relationship so we couldn't get together. I know this girl will be single soon and believe she still has feelings for me. I dont know whether to stay with the girl i have now or go to the girl that i've had feelings for a long time.
