My boyfriend likes my friend
I feel really stupid asking about this on the internet but I don't know what else to do. I think my boyfriend likes one of my friends. They always call each other. Like right now he is in the other room with her and a couple of my friends and I just heard her say THREE DIFFERENT TIMES to him "ok i'm going to call you in the morning". I've been dating him for almost four years and we live together and I don't know what to do. I can't afford the rent in this apartment by myself, but I know that's not a good reason to stay with someone. I don't WANT to leave him but sometimes I feel like that's my only choice. I'm so sick of all the flirting and the phone calls. What shoud I do?
