How to overcome a break up

Hey girlies I just recently got out of a relationship and it hurts a lot. We are both hurting but it seems right to end it bcus we’ve been on and off for the past couple years and he says it’s not right which I believe is true. I wish things were different and he was my first true love so idk how I’m even gonna get over him and not think about him everyday. What do y’all suggest? Do you think it’s good to have each other on social media?
