Can’t take him out of my life 😩

So in 2018 I meet a guy and we became friends with benefits. We would meet here and there , he used to be with other girls as well, and even tho I knew this I keep seeing him. Last year, he told me that he was just seeing me and another girl which I knew her because she had the audacity of creating a fake Facebook and contact me. At some point I had feelings for him , but I got distant , and now I fear that those feeling are back. I found myself caring wait tooo much and I’m so hurt even tho I shouldn’t be. I know we have nothing but lately I been felling like a piece of shit , I feel like I’m not giving myself the respect I deserve. I’m not ugly and I have a lot of boys wanting me, but it seems that I only care about this guy. He has not respect for nothing and I feel stupid for letting myself been treated bad. I try blocking him of everywhere , but then he find a way of texting me again , I don’t find the strength to do it. Last year around this time I had a really bad depression which led me to hurt myself and I don’t want anything that would bring me down, this is my first time posting in here , I really needed to take this out of my chest because I have no friend to talk to. BY THE WAY I’M 22
