Girls, girl/girlfriend says has feelings for me but wants to know more about me and the feelings to say yes?

girl who is a very good close friend (both been through life stuff) who i have known for 2 years says has some feelings for me but wants to investigate her feelings and also know more about me before saying yes. Has turned down someone else too for me but...

whats this? she does have childhood issues and parental issues and stuff. is this a trusting me thing? she says she has feelings and knows me quite well so why the investigation as to how i am?

i have loved her for a long time and she knows that, but I don't know, trust issues i guess.
