I had a crush on a girl in workplace, and I noticed her looking at me multiple times. At a party, while I was drunk, I blurted out that I like her and later on the eye contact increased a little more.

But she never replies on text fast enough, like there is at least an hour of delay (even though is on her phone).

Funny thing is, I discovered recently that she has a BF somewhere else..

How do I interpret this?
