I’m in love with a really close friend, I think she feels the same way, what do I do?

A little background, it’s kind of a strange situation, we have been friends for 2.5 years and in an organization where members are not allowed to date each other. We text each other constantly when we’re at home, and hangout a lot when we are near each other. I don’t know what to do. She texted me at like midnight the other day and told me that she broke up with her boyfriend. She sends me multiple Snapchats a day, and texts me all the time.
On the others hand she is naturally very flirty person, and I don’t want to jump the gun, but I really do think she’s into me
The last time a group of us went out to drink, we got really drunk and she kissed and hugged me a lot, but she was hugging everybody, and kissed some other guys, she is really flirty when she’s drunk
