Please, I really need some advice

I used to work in a small pub in a neighbouring village. Everything was fine, and everyone seemed to like me until I got together with one of the regulars. Then my bosses daughter decided to hate me. She told me that I was ruining my blokes life coz there is a age gap and he'd be better off without me!
Anyway, despite all this me and my bloke stayed together. Then she told me she wanted me out so i quit. Because its my man's local I go down there maybe once a week, but when she's there she says callous things about me, says I'm a immature kid etc. I'd understand if i had done anything wrong but It just seems that I'm being victimised. She has a go if I put Britney on the juke box coz 'thats not her type of music'.
I really dont know what to do. I love the people who go down the pub, and dont feel I should cease going down there just coz of her.
What can I do?
