<human>: Be sure to explain in detail with line breaks.

It bothers me quite a bit more than I'd like to admit. I've tried rationalizing with myself that it's okay and that she's just looking (which I definitely believe is the case) however I don't know how I should act.

We were out playing pool the other day and these two guys pulled up at the table next to us, suddenly she glances over for a second. Then I begin to notice that after every shot I or her takes she's glancing over very briefly (1-2 seconds) and looking back. I don't think she noticed that I caught her because as I started paying attention, she looks at a lot of men as we walk from head to toe and side glances with her head looking forward if she finds the men attractive.

We're both each other's first real relationship if that means anything, however, I don't go off looking at other girls with her or when I'm alone. She really is the only girl I see, and her looking at other guys worries me that I'm not enough. It practically invalidates that she's told me that I'm all that she sees as well, and I worry that she's lusting over these other men, even if it's brief.

Should I confront her on this? I don't believe she would stop even if I told her it bothers me (especially when I'm with her). I'm definitely not going to start checking out other girls to make her jealous though.

Give me a shortened version of the text
<bot>: My gf checks out other men even when we are together, it makes me a bit mad and I'm not sure how to act on it.
