I was fucking this girl exclusively last semester. It was great and I thought I found a unicorn and someone that I could settle down with. We go on our winter break and she starts to change towards me. comes back and just wants to be friends, basically wants all the benefits of being with me without fucking me( attempting to cuck me). I hang out with her and friends thinking I could easily persuade her back into how things were. I find out that night she fucked some dude over break which made sense why she changed. I dipped out and so far have ghosted. I fucked other girls over break too but made me mad a plate would do that to me. How should I proceed?
