I [24f] have feelings for a good friend [28m]. This is more complicated than it really sounds. I also have a boyfriend and he has a girlfriend. I know I am a scumbag for even wanting something to happen with my good friend and me.

This friend and I have been hanging out for over a year. Things between us have been just drinking together and playing pool nothing serious. Over this year I have developed feelings for him. 

I feel like a jerk because I have been dating another guy for about 11 months. I know it's not fair to him. Our relationship hasn't been too great and we have a lot of issues. This good friend has always been there for me when times got rough and I for him. The good friend is in a long term relationship. I feel like total jerk because I don't want to ruin that for him.
<bot>: I have feelings for a good friend and we are both attached. I am at a loss as to what to do.
