Most Helpful Guy
Well first of all, this is why I stopped dating girls who are under 21 as soon as I was old enough to have such a standard (I'm 24). The reason isn't because I'm an alcoholic that feels my relationship would fail because I can't go get drunk with my GF. The reason is that I realize that once people hit 21, the bar scene becomes your standard place to socialize. It's the watering hole for adults. Even if you don't drink much (like me), you soon realize that most socializing happens at the bar, watching sports, getting food, birthday parties, holiday celebrations, weekend gatherings. It all happens at the bar. Knowing this, I fear that if I was 21 and she wasn't, we'd be spending a lot of our social time apart. She would be unable to socialize with me and my friends which I feel would stress the relationship, as its doing to do you guys.
I wouldn't call your Boyfriend boring. As a matter of fact he seems to live a rather normal life. I was expecting you to tell me he watching TV 24/7 and never leaves the house. He clearly likes to do things and socialize. I don't think this is entirely his fault. It's just the unavoidable truth that your not 21 so he's forced to leave you at home if he wants to see his friends.
That said, He should be aware of this, and make sure that he makes the most of his time when he is with you, and juggles his time between his friends and you accordingly. If he's out with his friends 7 days a week, then that's not good. I used to have a similar situation (I was 21, she was 18). One or twice a week I would go to the bar for a few hours with my friend, then come home and hang out with my GF. The rest of the nights I was all hers. On weekends when we had more time, we'd usually plan something that she could that involved leaving the house. Going to the zoo, swimming, shopping, a movie, a concert, etc. Also, don't get lazy just because you are a girl. You can plan these events yourself instead of expecting him to read your mind and know that you have a problem with how he's living his life. If he seems to reject your offers or puts up a fight about spending a day with you, then you have a problem, but if he seems willing to do non bar things with you, then your fine.
Dating a college guy won't change this, if anything it will get worse. Most college students are either busy with school or work, and when they aren't, all the want to do is get drunk and party. Most college age guys aren't really going to want nor have the experience to really experience things with you that go beyond the dorm room so to speak.
