Straying from the road taken [any further] would probably be to the detriment of reality, Kitty! Especially given you seem to be unendowed by greater means - i feel sorry for your wife in a lot of ways - but if she is indeed mean [as you say], well, perhaps less so! It is not known how this will turn out, relationship wise -- older sisters ...don't spoon...usually 😎 Stay positive and if she's not so mean, be nicer to her!
