my boyfriend acts like a douche bag and sometimes he is the sweetest guy on earth. he sometimes talks to this girl I know and he recently said you should come to my work to see me and stuff. he's never said ANYTHING about her and I know almost everything. I don't know what I should do. he swears he's not cheating on me but idk...maybe I'm just getting too jealous but he says that she's beautiful and such to her...HELP!
