I finally broke up with my crazy ex

In the being he was normal. We we’ve been together 3 years and it all seemed so good until this year he just went nuts, quitting jobs, freaking out on me and his co-workers on his family and ending up in a psychiatric hospital and when he ended up in there I knew I was pretty much done. I can gave him another chance and he was fired from another job a few days ago (he told me today) I just ended it. He’d constantly changes plans we made to go out and make excuses and after excuses for canceling plans/dates. He just became incredibly abusive and weird.
