Most Helpful Girl
Dear lord. She sounds like a psycho. You have three options, I think:
1. Text her. Tell her you think you should stop sleeping with eachother.
2. Next time you're with her and she does that, just stop her and say, "you know what, I'm kinda over this, I think we should stop". This is harsh, but f*ck, seems like she needs it.
3. Phase her out. It's kinda mean, but I'm guilty of doing it. You just slowly stop responding to texts/calls. First reply saying you're busy, and then eventually just... stop.
