can’t let go

my ex broke up with me about 7 months ago and i can’t move on. for the past 7 months i convinced myself he was coming back. He would always leave little breadcrumbs and it got me every time. he consumes probably about 85% of my thoughts it feels like. Well a few days ago he posted his new girlfriend and has been consistently posting her since. I have unfollowed him but that doesn’t stop me from going on my burner to look. Im actively really trying not to look at any of his social media. any time i think of him and how perfect i thought everything was i just try and sway my thoughts and remind myself he chose her. it’s just really hard and i really hate all the anxiety that comes with it. I just wanna be able to move on
