Am I not a likeable person to her or is it something else?

I'm not going to big up but I'm not a very hated person in general as far I'm aware, people are always are very nice to me and I always good to them but this server at a pub just makes me think she hates me, she's aware I like her, I think but I never had any chat with her. we had few eye contact but recently just stopped looking in her direction because I think she hates me, maybe then again she's pretty introverted with a small group of close friends and seems fine around people when serving.

A bit messed up and confused, any help will be greatly appreciated.

Thanks :)
