i agree with sara.
it’s okay for these guys to say ‘if you think negative, it will happen’ but they don’t know the reality of relatives who take pleasure in ruining relations between people.
i don’t know why your parents are doing this to be honest. doesn’t matter how much of a ‘diamond’ the guy is, unless he can stand up for you at every turn and make his family understand that you are more important than their phupoo, it is going to be very difficult to you.
life is hard enough without constantly battling against negativity.
it can be turned around but it totally depends on your father, his father and your husband. if they can all always take your side and defend you without making it too obvious, your MIL and phupoo will give up.
