No thanks.
I already have three EX-mother-in-laws.
You survived three? You should write a book :)
My future MIL had knee replacement surgery. I drove her everywhere for weeks and visited her in the hospital many times, got groceries etc.
Planned a vacation to Vegas with the works for fiance, because she was stressed from job.
The mother calls me one day, concerned i was taking advantage of her daughter financially to go to Vegas.
The whole trip was on me, even first class seats.
I just hung up.
