Most Helpful Girl
Something is not working out for her and like any lonely person is using you for the meantime. No person that breaks up and wants to return acts like this unless there is someone else involved. If you want to be a comfort for her, go with it, but do date others because this chick is not all there and probably will not.

She playing the field and using you as a safety net. If you want a realtionship like that it's all up to you. I would go no contact forever. Sometimes it can work out. but if this happining within three months and it doesn't get better then it never will. She gets to ride the cock carresel and gets the bennifts of a realtionship.
The reason why I know this it's because my ex pulled the exact same bullshit. But I went no contact after a week. And she use to live with two other people and one of them texted me after two months saying she "had" someone over easy within a week.
Now from her point of view she can make her new guy jelious by saying my ex and I are on good terms and she gets to manipulate him and knock down his self-confidence by saying she has options if you don't do things my way.
This is what you do just to give her a taste of her own medicine. Text her while you are out. "I'm at this crazy awesome ( vip somewhere got bumped to first class) party just thought I would give you a ring.
Find the hottest group girls around you NEVER aproach women when there by them self. tell them you had a friend ditch you because he wanted to go on a blind date. get a group photo and add it to your snap chat story.
If you think that is harsh that is just a taste to what she is doing to you and she is making you dink the whole bottle. Then when she starts texting you back that night ignore her. Then realize you deserve better and move on.
