Restricted phone calls.... don't answer!

This evening I received a phone call from a man who asked me out once before but I declined as I already had plans. His name is David. He does business with lawyers in my building I believe. I think he is a lawyer in fact. Well, after David initially asked me out he never called again, nor did I. Life's busy, as if I didn't have enough going on... So, back to tonight's phone call.
I answer the phone and he starts in with this love schpeel about wanting to be loved and asking if I want to be loved. And what I thought about him. If I wanted to date him and love him, and be loved by him. At first I thought he was drunk and as I'm laughing and trying to step out of the shock of what he's saying to me, he says, "you don't even know who this is!" I tell him I do - "This is David" I say. I'm laughing a little still trying to figure this out... and say that I don't know if I'm ready to love again because I just got out of a relationship and feel like I need some time to myself. He says "I didn't know that you just broke up with your boyfriend, did I?" Yea! You did!! I went into the scenario of when I told him what was going on when I told him I was newly single, and he replies "OH I know who this is!"
WHAT? You don't even know who I am and you're giving me this whole love line!? He then proceeds to tell me "I take it back, I don't want to be loved! Not by you!"
What?! That so mean! He says, "I remember I asked you to do something and you rejected me and never called me back or anything." I told him yes, this is true and for this I apologized, and told him I have literally had very little time with school going on right now. He replies, "Well, since you were nice enough to apologize, maybe I do want to date you! Do you want to date me?"
This man is clearly crazy. I told him that as cheesy as it sounds I really don't have time to date right now. At that, we wrapped up this bizarre conversation and said goodbye.
