MIL always interrupts every conversation into how it relates to her without letting anyone else finish. My son's graduation dinner yesterday turned into what she studied at school, how she was the oldest in her graduation year. I replied yes, you told me this before and she kept talking. So I said it louder, you told me this before.
She got visibly upset but kept talking.
After 22 years of her I have had enough of her boring monologues and inability to let someone else have a moment. When I was sick when I was pregnant she kept talking about how healthy she was and how long she breastfed for blabla.
Everything i say results in her relating it to her.
Plus hours of nonsense about train times, shop opening times, What's in Sainsbury's.
My husband is quiet and unbothered by her blathering, so she gets away with steamrolling us.
AIBU if I interrupt her and say you told me this before.
