Been dating this girl for 6 months, virgin, now LTRing her.

I went off town for a few days, and things were going well, besides her shit testing and trying go turn me on so I don't look at other women. Waiting eagerly to see me and sleep at my place cook me food and crap.

So, randomly I spark up a conversation about a dull kid I knew in school, and she said that he followed her on Instagram the day we were in a bar and he was there, all of us in separate groups as I argued with her, and she follows him back, claims on her own they didn't speak in DM without me asking and says she saw how I looked at That girl next to me. It's true I did fck around with someone after the night but why mention it without being asked?

Then she uploads some crap story about respect, goes Mad because I compared her now childish behavior to my ex.

What to do? How to proceed?
