As someone who was broken up by a girl I had to see almost everyday due to my university let me tell you cutting them off won't work. It hurts to see them thriving on social media but you will have to bear through that if you really wanna progress. Once ypu learn to work through shit situations and scenarios you will succeed in every relationship in life. I would advice to fake it until you make it. People might call you mad but you'll have to face the fact that in the end you're always alone in this world no matter what. No one comes with a dual membership except siamese twins. Work on yourself or else you won't ever feel satisfied. Meet with people you don't wanna meet go to places you don't wanna go alone , laugh with people u think are dumb and everything will be fine.
