We’ve somehow got ourselves into the situation where all of the contact my MIL has with us goes through me. All questions about arranging visits to see my DS, all questions about how we are, arranging family get together all goes through me.
Then at Christmas MIL got very drunk and had a go at my DH for being a rubbish son and never speaking to her! I told her gently but firmly that she should start contacting him rather than going through me for everything! They have had a strained relationship for several years and to be honest my DH has been rubbish at contact in the past (when he was a teen/young 20s) but I think now he’s genuinely hurt that she doesn’t seem to bother him, and I get annoyed and doing the ‘wife work’ and keeping their relationship going. They will literally never speak and we don’t live close so only see her every few months, then twice a year or so they’ll get drunk and all the dramatics start 
AIBU to tell her again to speak to her own son every once in a while!?
