I need advice on marriage.

I got married just six months ago. The first month with my husband was just wonderful. But then, when we lived together for a couple of months, he told me that he didn't like the way I look after our house and cook. I try to please him, look for new recipes, even sign up for cooking classes, try to clean the house more often, but he still doesn't like what I do for us. It got to the point that he threatened me that he would file for divorce in Washington state. I'm so afraid that his words will turn into actions. I am very afraid of losing him, because before we had an ideal relationship. How can I please him? What should I do?
