Does this girl like me back ?

For about a month now, I’ve started to develop feelings for a friend. She’s into girls too, so i don’t need to worry about that part, but I’m just not sure how she feels. Multiple times we have had very flirty conversations and have even expressed wanting to kiss eachother, but I don’t know if this is something she does with just me. I had a hard time with a seperate person a few months back, and it’s slightly messed up my view on romance.

Lately that seperate person got into a relationship, and i’m really happy for them because i’m finally moved on. But what my current crush said sort of made me question a lot of things. She said that the other person was trying to make me jealous because they miss the feeling of having me around/me being basically obsessed with them. My crush definitely wasn’t happy, in fact she seemed a little mad. She’s also seemed angryyyy when a guy who used to like me was acting like he still liked me. I think it’s the fact that she doesn’t really like me hanging around him is why i think she MIGHT feel the same.

but i also have no idea how i’m gonna tell her..
