I was in a messy breakup a few years ago, I take 100% responsability for it. I hurt him and he made it clear he didn't want to speak to me again. Fast forward several months and he contacts me because he blamed me for his new girlfriend breaking up with him. I wanted to help the situation but obviously, I couldn't and we stopped speaking again. Now years later he contacts me again to check in and see how I'm doing. We breafly talk and then he goes silent again. What does this mean? I know he doesn't want anything to do with me but why contact me?
