So about 2 months ago my ex of 1+ year and I started college at the same school. I broke it off with her on the third day here and i've hooked up with multiple girls since, but its hard to stop thinking about her. We've fucked at least 10 times since we've been here, she'll straight up come over to my room and i'll give her dick and she might stay the night or whatever and while she's with me its like we're dating, then she'll leave and we straight up will not text eachother unless shes trying to come over again or if she asks me to get food or something. She gets extremely upset hearing if im with other girls while telling me she loves me and saying that she needs to "improve herself" before she gets in a relationship again. Is this a bad idea? Is it bad that a part of me wants her back? The last couple days we have had 0 contact but I know shes going to text me again and i'm not sure what I should do
