<human>: Can you summarize the given text in a few sentences?

So we dated for 4 months, but I've never connected to someone so powerfully as I did with my ex. Most of our relationship was spent long distance (about 2 hours apart), but we saw each other on most weekends. Everything seemed fine when she came back for university, we had a couple dates and kept the texting going strong. And then she went from happy to see me one Wed. to breaking up with me on the next Wed. 

I'll admit I didn't handle it the best way, but I didn't say anything intentionally malicious. She said she wanted to be friends, but I said a) I wasn't sure if i could see her with someone else, and b) I wanted a clean break, by which I meant I wanted to walk away right then. I thought over it for a few days then messaged her about how I did want to be friends. She was pissed about how I said I wanted a clean break, and said she didn't think I was going to be ok seeing her with someone else, despite me saying otherwise (I'm not the jealous type. She knows this). She ended it by saying she needed space and didn't think being friends would be a good idea. Though she did say we may talk about it in the future.

So I've respected that. I've given her space and not reached out to her. In the mean time she's cut every contact that we've had except Fb for some reason... that one's confusing me. 
But my question Is:
I'm having a hard time getting the wind back into my sails. I bounce between being fine and just utter apathy. I'm a university student but I just can't seem to care about it. I still get good high marks despite not really trying so it's not like I can focus on working on that, I don't really feel like hanging out with friends or family, and I don't feel ready to move onto another relationship. So what should I do? I'm normally pretty good with pulling myself up by my bootstraps, but this breakup's gotten under my skin and is messing me up :(
<bot>: Really cared about this girl, broadside breakup, and now I'm putting around the kitty pool trying and failing to get my bearing. Advice to get back onto the high seas?
