Does this mean I’m the problem?

So I’ve been single for a long time. I’m only 21. But it feels like now is the time to start making more serious connections. Accept whenever it happens I get nowhere. I finally had a potential after months off talking to no one. He gave me his number and everything. Within the first three messages he just never responded and continued posting on his story. I didn’t want to feel shitty about it I just do. I feel like something is wrong with me. I always get ghosted. I didn’t even get to say much. Like what is the issue. Why can’t anyone learn to know me? I’m just sad. I wanted this to maybe go somewhere possibly. Now I just feel like I’m dumb and going to be lonely forever
