Recovering from being the crazy ex?

Anonymous
It's been about a month since he broke up with me over something hurtful I did. I spent the first chunk of weeks profusely apologizing (letters, emails, two visits, calls) all of which he responded to. Then I called him to address some new things on his end that came up during our closure meeting. We talked for about an hour on the phone and I learned that he dumped me more so because "we are not right for each other" and he "fell out of love months ago." The thing I did just confirmed for him that I am not the one. The conversation was civil, but when I got off the phone I flipped out like crazy. I felt like he had led me on the whole time ... like I spent the better part of the month apologizing for what I did when in actuality there was much more to his feelings about us.

So how did I flip out? Let's just say I called him too many times in one day, I went to his place unannounced to try to get my stuff but he didn't answer so I left w/o making a scene, I left a couple of "screw you" messages, left comments on his fb page telling him to finish removing my pictures, and sent a couple of emails. He's no longer talking to me at this point. This was all last week.

I know, I know. I went nutso. It was childish. That is not to be disputed. What I want to know is what can I do so I am not labeled the "crazy ex"? I've already decided not to contact him again but should I write an apology letter for my behavior? Any suggestions?

Also, assuming he does really love me and would eventually want to get back with me (which I'm 99.9% sure will NOT happen, but I'm just wondering), did I just screw up my chances? Can I bounce back from this by just being on a good behavior this day forward?
