AITA??

We went no contact (or just about) with my MIL when our second was born for… many many many reasons. This is her last text to my husband and he never replied. Do you think he should contact her about this or no? He says he wants to talk to his mom but he tried after our baby was born and she ended up texting three paragraphs to MY dad about how I’m keeping “my” kids away from her..
