Why should MIL like or approve of her DIL?

Re: Why should MIL like or approve of her DIL?

This experience may best describe the reality. I guess what surprises me is the expectation that a MIL must automatically like or approve of the DIL and when she doesn’t, then you see threads popping up about how much the MIL hates the DIL and is making their lives a nightmare and that’s so unfair.

So long as there’s no naive expectation by the couple that they will be playing happy extended families from day one, I think maybe peaceful and respectful co-existence is possible later on.
