Lynn, I am writing you under the pressure of my best friend

My best friend broke up with her boyfriend. Although she is all depressed about the break up; I am happy they are no longer together. Joe hit on me first and I was about to give in but one day we all met and my bff told me that she is interested in Joe. As a good friend I let them be together. However, I’ve been always jealous and I hated myself to let such a good man goes away. Two nights ago, Joe and I met at the Spurs Game; we hit it off pretty good and we ended up spending the night together. Joe and I decided to be a couple. I am torn between friendship and love. My bff is sad; she worries me but at the same time I am falling more and more for Joe. Do I risk my friendship with Gill or do I let Joe go to save our friendship. Or should I try to hook them up once again
