I'm pretty sure my crush is in the closet. What can I do without making things worse? Any advice is appreciated. (context in description)

So a few days ago I started chatting to my crush (this is outside of school and in a program i would not share for reasons, and the next day on Friday, in school she blew me a kiss and i chuckled smiling) after one of my friends said that she said she was straight (my friend had said that she was gay or smth along those lines) but she said it hesitantly. I know shes closeted, its obv tbh im just wondering what do I do? we don't talk much but i know how it feels to be in the closet. I came out to my family just over a year (last year in oct). And it was hard and when I was in the closet it was tiring, and I hated myself for who i am. I am better now I just hate different parts of myself, but I just don't want her to feel like that because it feels bad. I want her to feel comfortable talking to me about anything and idk what to do about it.
