Before I start, yes I have oneitis. Been banging this chick for maybe 3 weeks and since I met her and she's texted me every day and always answered super quick so I'd respond pretty quick which was my first mistake. after the 3 weeks she tells me she wants a break from talking and I say ok. couple days later she hits me up and we fuck. That was the last time we had sex, ever since then she's answering slower and showing less interest. We hung out maybe 2 more times without sex. I told her we're gonna get drinks tonight and she said for the first time I'll let you know and that's when I knew she's lost interest. Before someone says fuck other girls, yes I'm fucking other chicks but she's the only regular I have right now.

I'm already trying to move on from her but I wanna keep smashing. What should I do?
