thotful, it's possible you're over thinking this a bit! family aside, if someone else basically told you they did not like or approve of your wife and feel that you SHOULD get a divorce, just how much more of your precious time would give them? and why would you TRY to spend time with them?? after they have called your dear wife names???
some people are best kept at a distance. with little to no contact. we totally get to make that call not matter who they are. we let them be, let them have their opinions, and live our own lives without their negativity. LIVE AND LET LIVE.
