My sister's husband always compares her looks, cooking, bringing up kids with me and his sister and thinks that we are better. This breaks her heart. She supports my BIL financially and works hard the whole day yet he wants a "perfect" wife. How does one make him realize her worth?

Hi, i think its his ego that makes him put her down as she is already doing a lot, very few men appreciate their wives doing better then them..if its really bothering ur sister ask her to go for counseling n take him too, a 3rd person perspective will really help n her hubby's underlying issues which make him do all this will also be addressed.
