I thought that the issue between my MIL and me was that we just came from two different "worlds" until last year...
My husband and I have been married for 10 years, no kids, she is desperate for a gandchild. Last year she said to me (without my husband present of course) "Do you think C would have married you if he had known you didn't want kids?"

- because it's all my fault. She also asked another entirely inappropriate question (which I won't post here) in the same conversation. I was so stunned all I didn't say anything. When my husband confronted her about it later she said "It's not my fault Brandi can't have an adult conversation". I'm sorry, but in my opinion that is not an adult conversation. I would never say that to anyone, not even my best friend. I assume if two people get married and stay married as long as we have it's not because one of them got suckered into it.
There are many other incidents, but this is not the correct message board for them
