So whilst on lockdown DH and DS have been taking walks locally with the dog and FaceTiming MIL whilst out and about for their daily exercise.
MIL texted DM the other day to ask how my grandmother was after losing her DS and DB within 12 hours of each other. Which was nice of her. Anyways, during the conversation via text, they got talking about how difficult it was not seeing the grandchildren during lock down to which MIL told DM that she had been on walks with DH and DS along the beach. No details about it being via FaceTime. Just made out that she had been in regular physical contact with them. Of course DM got really upset - she's finding the lock down quite difficult.
Anyway, after talking to my DM about it (DS told me about the situation because DM didn't want to cause a fuss and start any arguments) I told DH about it and asked him to tell MIL that she had upset DM and to be more considerate with her explanations or descriptions in future. DH doesn't see the issue and won't say anything to MIL.
AIBU to insist that DH has a word or should I do it myself or should I just leave it?!
