I had behavior like this once. I broke off the relationship, and I knew without a doubt that was right for me, and that we’d never be right together, but it was very painful.
I blocked from social media only because of how excruciating it was to have him brought to mind — this lasted for over a year. Now that so much time has passed, I peek in on him just like I do old friends from high school.
Either it’s a deal like that, driven by conflicting emotions, or she is trying to manipulate you, IMO.
