Excessive Drinking and Partying...

Okay so I just broke up with my boyfriend for his tendencies to hide stuff from me. I got tired after he didn't tell me his ex was stationed at the same base as him for the past year and a half among other things which I don't care enough about anymore. That was the last straw.

ANYWAYS (sorry had to rant about that)

I'm back in the dating pool and I met this really nice guy and I like him and he likes me. However, for being in college, I'm rather reserved. I go to the occasional party and would much rather focus on classes. I drink wine every now and then, sometimes I get piña coladas, nothing wild. The thing is that this guy parties and gets blackout drunk waayyy too much. It's kind of a huge turn off. How do I tell him that? Or do I not tell him?
