Get her back even if she is dating someone
Like they take the shape of whatever they get into. None of you who have never been in love get to judge the situation, alright? See the deal is, she's used to having you around so when you suddenly stop all contact, she'll wonder what's going on and initiate contact. When you do start talking, have absolute control over your feelings and make sure that you do not fall into the same trap again of being at her beck and call. That last bit about her starting to question whether she did the right thing? And of all the tumults that a relationship faces (and those, there will be many), the need to want your ex back when she is already dating someone else is one of the toughest situations to be in. This will get her into a questioning mode, at least, and she'll begin to question whether she did the right thing. Maybe by talking about some other girl or by showing her that you've moved on.When sentences like 'What if we were still together', 'Do you miss me' and more like the same start to make way, that is the time you could initiate the 'Have you thought about getting back together conversation'.
If your intentions are right and fate is with you, maybe the day the two of you will be together will dawn bright and clear.
Sometimes people are addicted to the intense feelings of being madly in love. If it is truly Limerence, with its strong pull of an increase in dopamine in the brain (and lots of oxytocin), than it’s likely temporary and could “spend itself broke” faster than a politician.
It could also linger a bit if your ex is trying to prove to themselves and to others that it’s not a rebound. That shelf life will be shorter if you stay in no contact.
Not only are they attempting to hurt you and to toy with your emotions, but they are using another person in order to do it! Your ex’s response to this will often be intense curiosity, which is a precursor to attraction.
Because your ex feels your continued distance, the new and shallow relationship will begin to lose its appeal. Because if yours was for longer and was serious, than your ex can feel the difference.
