<human>: So, me and her met about a year ago, and since then we've been really good friends.

However, about a month ago, she started dating my best friend, and we've gotten even more close as she asks me for advice on him.

We both confide just about everything in each other and we are really close.

Part of me, is beginning to think that she has some sort of a thing for me. Our conversations have been getting more and more suspicious for friends. We talk about things that should generally not be talked about by just friends. 

And lately, she has taken to calling me lover after an auto correct incident when saying goodnight.

Can you condense the text into a few key points?
