Maybe she's just being nice or friendly to you...because both of you are in the same position (breadwinner of the family).

TALK TO HER....demmit (hehehehe)...so you would know what to do.

Coz right now, boy...you're scared of things that will never happen. Why?

-you and her are just friends (or mutually interested)
-you're not even in a relationship

Yet you think of incoming responsibilities on top of your existing responsibilities.

Tsk :/
