How do I not let it bother me?

Me and my ex broke up a month back (I’m 20, he turns 22 this month and we had a 6 month sorta hot and heavy relationship). He owes me 2k. After the breakup we unfollowed each other and shi and from my 3 accounts, I blocked him on my public one. I’d stalk his business profile about trading occasionally. He did text me a lot (about how he feels crap about breakup, wanted me to be happy etc) but he was a toxic and emotionally abusive narc. By the time i responded about his message and asking my money back (10ish days later as i needed time to process it) he blocked me on iMessage so he never got my text. I lowkey gave up on getting my money back. Now I noticed he blocked my accounts tho we unfollowed each other. And for some reason it bugs me. The breakup deffo is smth I needed and I am more livelier and happier without him being in my life but these sorta actions do bug me. I lost 20 pounds, had panic attacks and self harmed when I was with him. He managed to brainwash me and isolate me as well. I don't know what to do or how to get my mind of this and move on. For my own personal development shit I have been avoiding going on dating apps tho I wanna go on dates because I know I need to work on myself in lot of ways. I don’t know why is this bothering me. Part of it has to do with the money too. Any solutions?
