I'm gonna guess that he actually DOESN'T like you and he HASN'T forgiven you and he's just messing with your head. Which you are letting him do by being borderline stalker-ish.
He's not going to chase after someone that isn't worth it. If all your doing is being clingy for long periods of time, that makes him run, and never chase you. The way to do it is to make him run but leave, and have him want to come chase you (example, to initiate with you for once).
To get this to happen, have a great time with him. You say you know him, thats good. Take initiative and go do something with him that he enjoys, keep the conversation playful.
I am sarcastic and usually without the intention of hurting people, but many people misinterpret it as offensive. Hes probably doing the same thing. Just play around with him the whole date, laugh at his sarcasm and make him feel like your fun and playful.
Then just wait a bit. He should respond to you before you initiate back. Good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
