I first started talking to this guy with aspergers in the middle of 2018. He asked me out, but I said I wasn't ready for a relationship so I stopped talking to him. For the next 6 months, he proceeded to call me once a month every month (6 times total) despite me never picking up.
Finally, after 6 months, I answered his calls because I felt bad about it and we started talking. In these next four months (end of 2018/beginning of 2019) we talked every night up until 4 am. I started developing feelings strong feelings for him, and him for me, but I wasn't ready for a relationship (due to many personal issues which I won't discuss). So after these four months, I told him I couldn't speak to him anymore and he left it at that.
About a month later he got another girlfriend. I noticed that for the next several months (till August 2019) he kept tabs on all of my social media (i.e. watching all my instagram stories and even liking my first ever post on instagram). Around this time, he sent me another message and we started talking again. He kept asking me out, despite having a girlfriend.
It's now the end of 2020, and he is still waiting for me to go out with him. We did agree to be friends, and only act as friends, because he had a girlfriend. But to this day he insists that we go out.
This persistence though, has been something my friends have attributed to as some sort of obsession with me. What do you guys think, do you think he's actually in love with me, or is it something else? Is this normal aspergers behaviour?
tl;dr: guy has pursued me for 2.5 years and is still waiting
