Still not over him

It’s been 5 months now since my 3 year relationship ended. He didn’t want me anymore out of no where and began ignoring me more and getting meaner. I can’t believe this much time has gone by and I think about him all the time. He was my first everything and he threw it away so easily. We still have each other on social media and he even has his snap location on and for some reason has me able to see where he is right after we break up. I try not to look but it’s hard. He’s on sites where u talk w people and uses the pic I TOOK of him which is his best one. Apart of me wishes he’d come back but after the hurt it’d never be the same. Advice to make me feel better 🥺
