<human>: (Relationship length.. since the early 90's when I knew him from high school) 

I was a nerd in school. I had no school friends and was teased mercilessly. My goal during school hours was to be as small and unnoticed as possible to avoid attention which was almost always negative.

A man who had attended my high school found me years later and recognized me. I had since grown into myself and had become much more confident. I'd realized years before that I was not the ugly, unlovable, or worthless human that my peers had encouraged me to believe I was.

Over the next few years this man contacted me periodically on Facebook. I was first very wary as we had never been friends. He'd been an attractive and popular jock back in the day. He kept hinting that we should meet. I was wary from the start and did not hesitate to mention that I was not available romantically numerous times. We briefly discussed my current relationship a few times. I expressed clearly that I felt that there were ulterior motives. He denied them.

We finally met up today in a place that was my choice. It was public but outdoors. We again chatted about my relationship status (not available). Yet he made a move anyways. Not long after that I said I needed to leave and we parted ways. At no point did he force anything on me. I said NO and he was respectful of it.

Not long afterwards he sent me a message saying that he hopes I don't hate him. I want to block him so badly but my brain is giving me so many conflicting messages. Maybe if I just ignore him from now on I won't have to block him and then feel guilty for it. Maybe I should reply to him and tell him how annoyed I am with his actions.

UGH.

Can you summarize the given text in a few sentences?
<bot>: Guy with ulterior motives gets clear messages that I'm not interested or available for anything but friendship yet pulls moves on me anyways. Why am I having such a difficult time blocking him!?
