>My ex continued to reach out to me, offering to be my friend, offering to be there.

False, he sounds very abusive and perhaps wants you to hurt yourself. He gets off on hurting you for some reason. He's very manipulative and a horrible person. You need to block him on everything for your own mental health.

You may have lost some people you thought were your friends, but they are not. They would have wanted to hear you out if that were so, and they didn't give you a chance.

It's time for a fresh slate, to find new friends who value your emotional well-being, then when you're ready, find a partner that isn't emotionally abusive.
