I feel relief I have not suffered a MIL that bad, in spite of having 3 of them! 
The first was a bit of an evil old trout, once she 'forgot' my birthday, even though she had told my H to make sure that he took me there on the day, and made me choose my own card!
Then 2nd was a bit controlling, butted in a lot with children, but her intentions were the best, so I took it all like that!
The 3rd, when my DP had too much to drink and decided to punch me decided I was overreacting when I phoned the police! Still, I don't have to go there again! We have a great relationship on the phone though! She is still my MIL, as I threw DP out for a year after this event and he had a lot of work to do to make it up!
Still, none of them were as bad as some on here.
