If you do invite her to a meal, make sure you are confident in asking. If she makes a fuss, play it cool, and say "it is just to celebrate Mother's Day, nothing more". Leave it at that, do not get drawn into R talk or start apologizing for asking if she sees it as pressure and starts telling you things.
Basically if she makes a fuss, just say "it was simply an invitation to celebrate Mother's Day, if you don't want to do it, it is no big deal". Play it cool, be strong, do not get sucked into justifying your invitation.
