What the hell should I do?

Yes for sure, kindly break it off with the boyfriend out of respect for him...you are focused on other things (a chick just being one of them.....)....be nice and break it off gently, firmly and make it final...that would be the right thing to do....your chemistry with him is kaput and better to jump ship now and save some of the hurt feelings....and then you can figure out what you like and why and all the other what not you talked aboutn avove in the long question. Good girl for recognizing already the right thing to do re: your BF...go for it, doll...
