Kneel down and beg everyone, why does my girlfriend send ambiguous messages to other men behind my back?

I don't know if she is stimulating you or looking for excitement herself. If you are a college classmate, the probability of coming from the same place is relatively small. High school students are generally from the same place. Maybe she will meet that man longer than she will meet you in the future holiday, so you never know what they will do then. What's more, she hasn't reflected deeply yet. It's really her fault. You can give her a chance and care more about her. If she's still like that, let go, because she's not worth it. If you are a man, you can be generous, but don't be a fool!
