what exactly does it mean if a girls says that you're cute?

I am in love with this girl and she is really caring.

now I told her that she is going to far by caring for her brothers and sister, because she is like caring for them 24/7. hm, i told her that that is the reason why i fell for her but that she is pushing it too much and that i'm afraid she might exhaust herself in the prosess. "i'm worried about your own health" i said, and she mentioned that I was "cute". what exactly does she mean with this, in this exact context? she knows i'm in love with her and stuff..
