I have a boyfriend we've been together a little over 2 years but I haven been thinking a lot about someone I go to school with and me and my bf live together and I love him so much and wouldn't do anything to hurt him but I just don't know what to do like I don't want to have feelings for someone else please help?? This kid doesn't want a relationship cause he's really busy but I still have these feelings and idk what to do
