It is true that a couple lacking proper communication is “more susceptible” but don’t think anyone is that strong. Why place yourself or your spouse in a difficult situation for no reason? Is it really worth it?
I’m not saying that it’s wrong to ever have another family over for a meal. FAMILY. Not couple. (At least if you have a family – even if you’re inviting a younger couple.) But you have to know yourself and your spouse and be open to things that you don’t like. I know that there are certain people my family is comfortable having and some that we try to avoid spending excessive time with as a family.
And eating out is completely inappropriate. Inviting has room for questions.
