I, too, am curious how long the two of you have been together. Has he always insisted on having this much say in what you do, or is this something he's just recently started?
Your additional comments about how he doesn't like it when you spend time with your girlfriends and doesn't have friends of his own only reinforces my gut reaction - he is being controlling and manipulative.
I'm not going to get hung up on the two glasses vs. half a bottle thing. If you read some more of the site, you'll see a lot of this comment: it's not how much you drink, it's how what you drink affects you. There is no "set quantity" that is the defining point of when someone has a problem with alcohol. It's what the alcohol does to you, both while you drink and after, that is a better indicator of whether or not a person has a problem.
I agree with the others. It sounds like there is a piece of this puzzle that is missing. I think he's not being completely honest about why he thinks you shouldn't drink.
