I 25F left my 6 year relationship 2 years ago. He is doing so much better without me and i’m just as miserable.

We got together when we were 16. Stayed together until 22. So we spent all our teenage-early adulthood together. I was obsessed with him. He didn’t seem to value me as I did but i know he cared.
All we used to do was lay in his bed and he would smoke weed, or mayne play video games. I remember going out together was rare because sometimes when we actually did go out I would be surprised at how tall he actually was. We went through a lot of things but i mostly remember that and also when I started drifting away around 6-8 months before breaking up. That’s when he noticed i was drifting away and he actually started caring but i was forcing myself not to care as much.

Anyways, i broke up with him 2 years ago and jumped into another LT relationship which I regret because i didn’t have time to grieve shit.

I see his post on instagram sometimes and he seems so much happier with a new girl, he has so many friends (he always had friends and even though I tried I didn’t really connect with them). But he does so many things now and he never did anything with me. I feel like I lost. Because i’m stuk in a part time job that idk if O enjoy and idk what I want in life. Im just lost and he seems so happy. Im so sad because I tried so hard with him i was obsessed, and when I finally had the courage to let him go turns out he’s happier ?))
