My boyfriend I leaving for college at the end of the month. I really dont think he will cheat on me and he's said he won't either I trust him. But my step mom was saying he's young he's going to want to sleep with other girls, and that if he does I should stay with him because it's just the teenage guy in him but if he does it twice leave. She also added if he was an older guy it'd be totally unacceptable. Me and my boyfriend both feel that if either of us cheated that'd be the end. I just couldn't believe she was telling me to stay. What do you think?
