Do I suck as a friend????

Hello, I’m starting to believe that maybe I’m the issue when it comes to friends. I think I’m just very oblivious, but most of the time my friendships just die out, and I can't help but think it’s my own fault they do. I really don’t put forth a lot of good friendship qualities; I’m kinda just a person. If you let me be your friend, I’ll just stick around you until you show me you don’t care about me anymore. Usually, friendships only last around a year to maybe 2 years for me before the other person gets bored and just ditches me. The thing I don’t really get is I’ll just let it happen, won't even bat an eye; it’s just a "oh, we’re not talking to each other anymore, alright" which sure could be a good quality to have, but like, sometimes it’s just like what did I do wrong? I thought we were cool? It seems like maybe I was meant to be alone, which kinda sucks to think about since I can't act like I don’t get lonely; everyone gets lonely but I don’t know this is kinda random but I wanted to talk about it since me and an online friend just randomly stopped talking to each other and it made me wonder about this again.
