really anxious sos

hey ladies, i really need some help. So i've been with my boyfriend for about six months now and he is the sweetest most loving man i've ever come across. i love him dearly but, ive been very worried lately. Prom is tomorrow and than senior weekend is on Friday and goes to Sunday at the beach. i can't go because i have SATs, but he's going. He has a room with a few of his guy friends and you know senior weekend is known for getting super drunk and doing crazy shit. i'm really worried that girls are going to hit on him or that he'll get really drunk and do something he'll regret. like i said i've talked to him and he said he'd never do such a thing and he's reassured me many times that he loves only me. but before him i came out of a relationship were i was cheated on numerous times, so i feel like it's taking a toll on me now even with someone who's totally in love with me. i don't know how to feel but i can't stop thinking about all the negative outcomes of this situation:(
