Wat should i do...?

Even though her boyfriend doesn't seem to take care of her - she's obviously in love with this guy & doesn't want to risk hurting him. If she leaves him then I would say it's ok to pursue her again but I think she's making it clear that she doesn't wish to talk to you. Maybe something changed in the relationship. Just let it go. You don't want to break up a relationship - even if it seems like it's an unhealthy one.
