Search Results: should i leave him marriage

So I play a lot of volleyball and I met my best guy friend playing. A couple weeks later a group of guys were going two stepping at one of my favorite places and they invited me to invite my girl friends because they liked my girl friends. So we went and of course I had quite a bit to drink and him and I kind of hit it off, but I kept him at arms length because I have a boyfriend. After that we stayed in touch because we run in similar circles. It seemed without even trying we became really close. He got upset with me because he didn't understand how I could be in a relationship and not with him when he sees all of the potential we could have. We discussed how we need to be friends and keep our distance. My current relationship can be best described as how I imagine a marriage would be. We do our own thing a lot and just enjoy being around each other. It is hard for me to see my guy friend anymore even though we are with a group of people because we are so drawn to eachother. So what is keeping me from being with him? I do really like the person I am in a relationship with and the guy I'm with is very into his career and preparing for the future much of like how I am. My guy friend is in his prime age and having fun and finishing school. He is 26 and it bothers me the amount he goes out, but then complains about where he currently lives (with his parents). Considering I have been on my own since a young age this is hard for me to understand how you can complain for what you don't have and yet do nothing about it. What are your thoughts? I know the guy friend would love me the way I need to be loved, but if I truly felt that strong why am I not with him? I also don't think you should ever leave someone for someone else. The main issue with my relationship is there is no passion, little intimacy.
