This goes for men and women - low self-esteem is a huge turn-off. It sounds like your boyfriend liked you. But if no matter how much you tells you he likes you and how attractive you are, you keep saying, "well I'm still unattractive and unworthy no matter what you say," he's going to figure "fine then, this girl isn't happy no matter what I say - what's the point?" I think your boyfriend liked you, but when you threw out the "I'm so ugly you should just leave me" card, he probably got tired or trying to convince you otherwise and took the out.
If you decide that you are unattractive and unworthy, just the thought will make it true. So why don't you try doing things for yourself to change those thoughts. Join a sport or hit the gym. Start an art/craft. Do something you like until YOU believe that you ARE attractive and worthy. Don't you ever wonder how sometimes the rudest and least attractive people seem to always have a relationship? Sometimes it just takes confidence. End point - whenever you go through a breakup realize where the relationship went wrong and think about how you can improve to avoid the same mistake from happening again.
BTW if you know that you're in a depressed breakdown mood, *do* something about it. Don't just expect your friends to "understand". Turn on some music. Read. Watch TV. Just because you're feeling down doesn't mean you're stuck or helpless. Regardless of how down you are, you are still always responsible for what you *choose* to say or do. That's why if you know you're feeling depressed, you can also choose to deal with it in a healthy, constructive way until the mood lifts.
That's just my thoughts.
I think he had this on his mind for a long time since you are at different colleges. I think your depressed mood about the relationship gave him an easy out--so he wouldn't feel bad or look bad.
Move on, but be happy about it.
You can do better.
