Most Helpful Girl
Sounds like she's playing you right now. She doesn't even make sense though. If she didn't love you, then she wouldn't care if you went with someone else. But like Zuzuka said, it's a case of wanting what she now can't have. If you paid attention to her again and begged for her back, she'd show no interest, I bet you. She sounds like a control freak.
I think she's lying about that friend too. She lied in the beginning to make you jealous, when it didn't work, she said she lied about it completely, almost so she could change tactics. Because you blanked her again, she's kind of punishing you with the idea that she's sleeping with someone already but I don't think this is true. She ignored the only rules you gave her and combined the two to get a reaction from you. It's not working so her games are all over the place.
She sounds quite immature tbh and not worth your time. I'd recommend not talking to her at all. Ignore her completely and you'll be able to move on quicker and easier. You should probably tell her that what she's been saying has made her look immature and you don't want anything to do with her anymore, before you stop all contact. She's not worth your time, seriously. I don't see any point in playing games with someone they claim they don't love.0
