My ex-boyfriend broke up with me 2 months ago because I was withdrawing from an antidepressant medication and was not acting like myself. He called me on the phone last night, hysterically asking to meet with me for some closure. I tried to maintain a calm and mature tone, and then he called me 15 minutes later saying that my tone was condescending and that I am "not worth it". The only thing I can think of that he would be upset by is that I told him I was concerned about him...because he was sobbing and screaming hysterically into the phone. He said he doesn't want to speak to me, which is fine, although we work in the same organization. I may have hurt him, but we only dated for 2.5 months total...isn't his reaction a little extreme? I seriously considered calling the police to patrol near my house last night because I was so afraid. How should I deal with this situation?
