I don't know what my girlfriend is telling me

I don't know what my girlfriend is telling me. submitted 42 minutes ago by whatdo00 My girlfriend and I are both seniors in high school and have been dating for about three months. Its been going pretty well and I like her a lot, but she hardly ever has any free time to spend with me outside of school. I decided to join an after school activity that she was in shortly before dating her so that that we could spend some more time together. Just this weekend though she let me know that she she is conflicted about me being there with her because she has some really good friends that do it too and she doesn't like having to divide her time between me and her friends.

She also told me that she feels weird acting like a couple when her friends are around. I wasn't able to come with her on the last trip that this group took, and she told me that she had a lot of fun and thinks that she wouldn't have been able to if I was there too. I asked her if she wants me to quit, but she didn't answer. I told her that she doesn't have to choose between her friends and me, and that we don't have to be super flirty around them, but she still doesn't seem satisfied. The kicker here is that one of her friends that she is referring to probably has feelings for her, she realizes it, and thinks it's awkward for us to be together around him. Should I be worried that she is not comfortable being around me with her friends?

Also, should I choose to quit the team to make her feel batter, even if that means that i'll hardly be able to see her?

I'm not worried that she'll cheat on me with the guy friend, but it is kind of worrying that she is able to have more fun with him than with me.
