My boyfriend wants to go out to dinner with someone of the opposite sex, should I be worried?

Anonymous
My boyfriend and I have been dating for 7 months. It's great and he's very sweet to me. I have had no reason to doubt him so far. Upon getting to know him better I realized he has had many friends who are girls ever since undergrad. He is very close to some of them and I don't really have a problem with it. From what it seems it appears to be a big group of guys and girls and he's formed good long lasting friendships with some of the girls. We are both attending medical school together away from our respective homes. It is our last year. He recently got into touch with someone on Facebook who went to his undergrad and is now attending the same medical school, just a year below us. She was in the same friend circle as him from undergrad but they never talked much or hung out. He caught up with her over breakfast a month ago. But then they started sitting beside each other and studying together in the same study hall, to the point where she was saving spots for him daily beside her. I explained to him why I was paranoid about it but I let it go when he assured me it was just them studying together. But then it escalated to her asking him to go grab dinner together as a break from studying. He tells me everything and asked me if it was okay. But I know if I said no it would turn into a huge fight where he thinks he's never allowed to have any friends who are girls ever again. And that the only friends I'm OK with are the ones he'd had back home. I think my fears are justified since you never know with these things. he thinks its completely okay to have lunches and dinners together, because he's allowed to make new friends. I feel as though this is a trend that might continue in the future as well when we venture into new working fields. I don't mind him hanging out with girls in a group, but I do have a problem with him meeting new girls and hanging out one on one. I mean I feel weird if a guy wants to hang out with me one on one and have lunch, even if I barely know him from undergrad. And initially when he started studying in the study hall beside her, he never told me. He'd just say he's saving a spot for his friend from undergrad (he didn't even know her that well in undergrad) or he's studying beside his friend from undergrad. It was after I asked him who this friend was that he explained. He just thinks everything goes as long as he's not physically involved with a girl. This is his very firm opinion and he's not budging. And I don't agree with it. But I don't think him spending the day studying with her and then having meals with her is a good idea. I don't know if I should bring this up with him again or not. I'd also like to know if I'm completely wrong/paranoid? Any advice would be helpful, I'm trying to let it go but the issue keeps coming up in one form or another. Help!
