Self esteem

This guy I know has been trying to talk to me since I met him. I finally decided to to message him years later as a friend to get to know him. We set up a day to meet then he canceled. Then we set another up lol and he canceled. Also he'll tell me to call him and when I do he doesn't answer? Which happened like 10 times. He views all my social media stuff as if he's watching me 🤷‍♀️ I feel a way because I was interested my feelings were kinda hurt? Even though I deleted him, why do y'all think he was acting this way? It's slightly weighing on my self esteem
