what are the issues you and your husband fight over?

My husband idolizes his sister so much and even at times that we have a misunderstanding with his sister because she has done a very grave mistake to me, he always sided with her. And there were times that he'd compare me to his sister, telling me how good a wife she was, and that her children are well-taken care of. It is not that I do not take care of our child, or that I have been a bad wife,it is just that he seems to put his sister in a pedestal that whatever she does, he wants me to do, too. I don't want him to push me around and let me keep up with the standard of his sister so we usually quarrel over that. Lately, we quarreled over the vitamins of our son, because he said I should use the vitamins his sister uses for her kids. And I hate that. Wouldn't you?

I am married for 10 years now and the issues over which we fight have changed over the period. Initially we used to fight over our dress. He was very particular about my dress and over the time we both have adjusted and things have cool down. Now we fight over issues which if we reflect are things that we actually want to see each other happy. Like i want him to have healty food, he dosent want me to work extra issues which finally say we love each other and care for each other.

we fight when I get insecure and jealous and that's about it. It happens about once a month, around PMS time, but luckily I didn't get PMS this month.
