I forgot in regards to equal time and community meals activities etc, don't push it if your wife is not ready. Having Rita in your home may be too much for her. Having rita in her kitchen using her utensils, especially right off the back, is a tremendous amount to ask.
First see how the meeting goes, hopefully its in a public place that is not a special placee to you and your wife. She how she deals with that and you paying the bill for Rita.
I know some of these sound trivial but they are concerns I had and have heard from others while doing research
