Confessed to my crush and we became very close friends

So here’s the thing

I confessed to my crush that I have a crush on her and she was absolutely cool with it and even smiled on seeing me the next day when I went to apologise to her coz I felt like I made it awkward.

So anyways that was four months ago and since then we have talked nonstop daily sometimes for five hours and sometimes for just an hour but we haven’t stopped talking and have become really good friends.

She even shares stuff with me which she doesn’t tell to the rest of our friends and I know a lot of things about her which she hasn’t told to a lot of people. She even asks my opinion on stuff she does and she always talks to me about her problems or whenever she’s feeling low.

Whenever I’m feeling low or am worried about anything she tries to cheer me up and make me smile and always makes me feel nice about myself so I do the same for her.

Anyways I was wondering if she’s acting like this with me out of courtesy because I’ve never seen her act like this with other people or is she interested in me and wants to genuinely know me?

tl;dr- Confessed to my crush and became really close friends so confused if she’s interested in me or what
