Ex blocked me. how do I stop feeling so sad and hurt?

my ex broke up with me two, almost three months ago now. we had issues communicating and we’re trying to work on things but eventually he said he no longer loved me and he felt unloved and that all of his efforts went to waste and gave up. he said a switch flipped and he didn’t care anymore. i begged and asked him to try and work on things but he said no. a week after the breakup we met up and he said his decision was final and there was no changing it. he told me he moved on and was talking to some girl he met online through video games. according to mutual friends, apparently they’re still a thing. they had plans to meet in person but i guess she flaked on him. that made me feel better in a selfish way but at the same time pathetic. someone i dated for almost five years gave up on me for a girl he has never met before. i feel like I've made progress - i no longer want to get him back and realize that i shouldn’t chase someone who doesn’t want me. he had unfollowed me on all social media, but i noticed recently he decided to block me on everything. why? and why do i feel so hurt by this? i can't even remember any of the good times i had with him, its like all of the bad memories and all of the hurtful words and actions are clouding my memory of him. how do i overcome this and stop hurting?
