I don't know how to handle this

I am 25M and I am seeing this hot realtor 35F. She is divorced and has a 7 year old daughter. I have been seeing her for last 8 months. We have been on dinner dates atleast once or twice every fortnight. Whenever we meet we smash. Recently we fell into an argument because I want to know what exactly she wants? Its been so long I want to make things official and she says wants to know more about me. I don't know what else she wants to know about me. Fun fact I am yet to meet her daughter.

Any advice?
