When we were planning on getting married, second time round for both of us, and I was yet to meet his mum, he said " don't expect a better class of MIL this time round"! He knew my ex and his family well.
Sure enough, before I'd even met her, she phoned to tell me that his ex " hadn't got a bad word to say about you"! I'd never met his ex, and they had been split up 8 years when we met. And then phoned 3 days before our wedding day to say they wouldn't be able to come as they were in Blackpool, on February, and we wouldn't mind, eh !??. They came for the service, ate, drank and off.
But then my ex's mum, in meeting his new wife to be and her kids, called me specifically to tell me how lovely she was, and how she was thrilled to have 2 new grandchildren. She never bothered with the ones she already had! And it meant they wouldn't be able to give my kids pocket money any more, ( 50p when we did see them), as they couldn't afford to give them all the same. If I ever marry again, I'll vet the in laws first!
