Single too long!!! 😒😒😒

I've been single since 19. Now 25! I've  been dating and had the start of relationships but never went anywhere. I think it's me! I always attract guys that constantly want to come over or only one date and that's it. I'm not a sexual person. So I don't come off slutty. I'm very independent and stable. How do I know if a guy is really into me? Any tips and advice is welcomed. Oh yeah I don't have any friends so I don't go out. Just work and home.
