Hi takenoprisoners! Sorry about your plight. I can only advise you to sit with your wife and discuss about her unpleasant attitude. She probably needs a reality check and look back where she came from. If she wants more, she better be working harder shouldn't she? Don't lose faith, give her chance and, if it doesn't work, get rid of her.
About your question, No not at all. I guess it depends on someone's upbringing. Either way, I wish you and your wife can sort things out for the sake of your child. Hugs!
