My ltr and I broke up for about 2 weeks over an argument. This isn’t unusual as we are very on and off and when we’re “broken up” we never talk to other people. This is a high school relationship btw.

However, During these 2 weeks I’ve heard she was talking to other guys consistently and having conversations with them, this is unusual because she has never done this before. She always ignored other guys and talked/texted none other than me. However in the past 2 weeks she’s been texting with 2 guys and she has been exchanging homework with her ex of 1 year.

I don’t know how to feel about this. I want to be with her but I just can’t forgive all of this I feel like. She used to be so innocent and would’ve never did anything like this so I didn’t have to worry about anything when we started dating a year ago but now I feel like she’s a completely different person. What do I do should I let this slide and tell her not to do it again or should I just somehow try it move on?

Last time we texted I told her we were done then I said I wanted to get hooked up with one of her friends and she told me to leave her alone

Any help is appreciated
