Has anyone been in this situation before?

Im am 26 and live with three male roomates. One of them is my boyfriend. Over the past few months I have been slowly falling for my roomate. The othe day he brought a chick home and I became a quiet wreck. i love my bf and all but im not in love with him anymore. My feelings for my roomate are very strong and I am definitly in love with him. I dont know the signs to know if he likes me too.I moved in there because I had to move out of my other apt because my roomie was psycho so my bf told me to move in there for a few months. I have been there ever since and they dont want me to move out. I have no money saved up and I am going crazy. What would you do?
