Does my friend like me?

We met in choir 4 years ago. I didn’t know her (Friend 1) very well, but we’ve become good friends over the years, just like I have with my other choir mates. We text frequently but don’t see each other often because of once-weekly rehearsals. She recently told me that she used to have a crush on me about 4 years ago but I’m not sure if she does now. One of our mutual friends (Friend 2) told me that it’s obvious that we like each other and that she wishes that Friend 1 would tell me the things she tells Friend 2. Does she like me, and if so, what should I do?
