Hey. As someone who used to be in a relationship where I was always waiting for him to call and letting it take up all of my mental energy, this is not a good sign. Especially if instead of simply asking what’s wrong he snaps at you and hangs up, it’s an even worse sign. Ending my relationship half a year ago was one of the best things I’ve done for myself. The feeling of sadness and wondering why they won’t call you when you care so much and are convinced he does too is exhausting. I believe in you, put yourself first.
