Should I let him go alone on New Year's Eve?

I am dating this guy, and he's not so perfect, the only bad thing is that he's an addict and he told me that he wanted to go to his birthtown for the New Year's Eve.
I am not afraid that he'll cheat on me with another girl, I'm only scared that he might get too high and too drunk and that he might finish the New Year's Eve in hospital........and I don't know should I let him go alone?He wants to go alone, but I know the gang that lives there and I'm scared for him..........what should I do?Will it be the right thing to let him go alone?

^^What Britt said.

Dating an addict is not a fun thing, if you choose do to so, you have to recognize the pitfalls.

I never tell him what he can or cannot do, and he probably doesn't want to spend that day with me beacuse he knows how much he's hurting me when I see him high....

My question is if he knows his getting high hurts you, why does he continue to do it.

To an addict, their addiction will always come first.

I know you might be scared for him. but you are not his guardian, i know you care about him but you need to let him prove to himself he can handle his own life.
