Not sure what to do

[TrentC]

Thanks Trent. I will get a lawyer, but how do I tell her I am doing this now?

You don't. You just go do it. If she asks, tell her that you thought about it afterwards, and you decided that you wanted to know what your rights are going into the divorce.

She also suggest keeping our accounts together until after we sell the house.

This is not my strong suit; you're better off getting advice from someone else (or better yet, your lawyer).
