Girl with a boyfriend sending me mixed signals?

I've known this girl (26) for a long time but didn't reconnect until recently when we found out we both had similar travel plans. I was going to book a separate room since I knew she had a long term boyfriend. But she invited me to stay in the same hotel room with her for a week, just the two of us (she paid). And we ended up going out for food and drinks every day. Eventually she wanted to go clubbing and we ended up holding hands and grinding together. But nothing really happened. And the next few days we were holding hands while walking around in public and cuddling. I started developing feelings for her and told her but she said she's still in love with the boyfriend. It's been two weeks since the trip and she still texts me good morning and good night every day. What's the deal here?
