Why does he still contact me?

So I used to talk to this guy a lot long phone convos/FT ….. I never met up with him despite him begging me, due to us getting in arguments and him having to many red flags. Make a long story short he was super into. Anyways still months later he still contacts me? He recently went on a spam and like all of my old and recent photos on social media within 20 seconds? He still asks if he can see me? He recently told me that he misses me. He never misses a social media post or story, and interacts with all of mine. He’s a good looking guy so I’m confused on why he still contacts me if I haven’t met up with him ever?
