This girl that i like and she likes me back but she has a boyfriend Girls would help me more on this question.?

I was texting her the other night and I finally told her that I thought she was really beautiful and she says "you're not bad yourself" which was pretty awesome. We text eachother like 100% of the day and her and her boyfriend have been having some problems like when they text all he says is yea and haha. She's very confused about if she should break up with her boyfriend and date me. I've been trying to talk her so we can get an emotional connection. What do you think I should do? I'm very confused too. She is a vey beautiful girl and I told her that she's the most the beautiful girl I knw and that no matter how hard I try I can't get her out of my head. Me and her talk about me and her kissing all the time.
