Re: advise required from.... married ladies
Im sorry, but if you have to find a 'work around', or a solution, then you have bigger problems to deal with, than just a one off trip back home. Respecting one's inlaws is perhaps the most basic ingredient to a fruitful relationship with one's spouse. If you respect your inlaws, no matter how much you fight/argue with your spouse otherwise, he/she will always regard you for the way you behave with his/her parents.
I think that there is no place for a comparison between 'your parents' and 'my parents'. Both must be treated the same. If your husband is ok with you buying gifts for his parents, and frowns when you buy something for your's, then frankly, there is a problem. You could buy something for your parents by going around him, but that wont solve the real problem.
You need to have a serious heart to heart with your husband on this.
