My boyfriend and a house party

This girl in my grade is throiwng a house party when her parents arent going to be home. Shes a bad kid, I try to stay away from her, like she gets in trouble a lot, hence the reason shes throwing a party. Theres gunna be alcohol there, and the problem is, she invited my boyfriend. I know thats not really him, but when hes underpressured to be "cool", he gives in, hes weak. I told him if he goes, id tell his parents. I told him this because I care about him, and god knows what hed do if he got wasted. Do you think I should let him go? If he does, I really wont want to be his girlfriend anymore, I dont want to be the girl with a "f*ck up" as a boyfriend. What should I do? Help!!! He hung up on me saying "ill do what I want I want to break up" I know he will get over the breaking up thing if I let him go, but I cant let him go. WHAT DO I DO?
We have been dating for a year I dont want to let him go

if you fell that strongly about it you should tell him that if he does go then you will break up with him. and if he still goes noing that you are serious about breaking up with him then he doesnt care enough about yalls relationship because if he did him wouldn't go if you didn't want him to.

this relationship sounds very poor. Let me quote you on " I dont want to be the girl with a "f*ck up" for a boyfriend"

I say let him do what he wants, you need to trust him. Dont worry about him. And, don't break up with him over something so juvinile, theres many ways this can be resolved, dont break up with him.

Lmao the part that got me was "hes weak" & "I told him if he goes, id tell his parents." First off referring 2 your boyfriend as "weak" in any sense of the word probably isn't good 4 the relationship. Secondly Nobody likes a tattle tell. Finally Confucius say "Woman who put mate in doghouse soon find him in cathouse. But seriously nothing going to happen 2 him & if it does then consider taking action but if you try 2 tell him what 2 do he'll probably do the opposite inspite of u

okay, first off, how old are ya'll?
second off, if you dont trust him then there isnt a very good relationship to start with.
honestly, I think your relationship is fucked up already.
if you are threatening him with things like "ill tell your parents" then, there is something wrong, because that means he cant trust you either.
