We've got a difficult relationship with MIL who is a narcissist. Most recently, she asked to me to cook for a dinner she is hosting (second family dinner in 7 years she's hosting) whilst I'm 4 months postpartum after my third C-section. All children are currently ill which she knows. She's never offered once to bring a meal or any support for the baby since little one has arrived. Also came completely empty handed when she first saw him at our house. It's unfortunately a negative pattern with her. So I said no to her request and she's responded passive aggressively. I really want to reduce contact as she's full of negativity and self importance and causing lots of unnecessary stress and drama whilst I'm running on empty, and sil has already reduced contact for the same reasons historically. However they're also looking after our toddler once a week, and I'm keen to move him to nursery an extra day but dh wants to give them another chance. Aibu for saying no and wanting distance? We have no other support.
