Brother,
Whylah u even contemplate asking your wife to stay with your mum.
If they can't see eye to eye, somemore your mummy all thorny on the
outside, I can guarantee you it going to be tough.
If you want to enjoy your life with your wife, forget about staying
with mummy. At least for the first few years dont let the 2 women
stay in the same house.
If you need to take care of mummy/daddy, wait until they really
need taking care of. Then at that point in time, get your mummy to
move in to your house! If your parents are moving into your place,
they know who's the master of the house. Until then please enjoy
life with your wife.
I can tell you are still pretty naive about this sort of things and
are not very good at managing your parents. Like children and
subordinates, parents needs to be managed too. If you stay with
your mum, you will have a big problem, its not your house u don't
set the rules and you're essentially your parent's guest. When if
comes to disputed you have no locus standi, so you cannot protect
your wife also.
Worst still when it comes to moving out, it becomes so difficult,
they will give you the guilt trip and make you feel like you are
abandoning them. So take the excuse to get out of there now.
Grow up and move out!!!!!
