I met a very sweet guy and fell in love with him. He says he feels the same way although he never said "i love you" to me. Problem is, he has a gf for 2 years and i believe they were best friends also and known each other for 3 years already. We know each other for barely 2 months. Yes, we are having sex. We can't resist each other. He had sex with his gf only once last year and we do it more often. I tried to leave coz I don't wanna destroy a relationship. But it's hard everytime and the relationship continues. Today, I finally made a decision to end the "illicit affair" and I hope I can stand with that decision. My heart hurts bad now. Bleeding. Am i right or am I wrong of letting him go?
