Every time we quarrel, my husband says divorce. What can I do to continue this marriage? But I don't want a divorce, because we have two children, and this time I am really angry. Well, my birthday is coming. I hope my husband can buy me a bag as a birthday present. Because I have been married to him for six years, he has never given me a gift, and he will not bring me anything when he is on a business trip in a big city. I remember once he went to Shanghai on business and brought a gift to his friend, but he didn't bring me a gift. I am really angry. I asked him why he didn't bring me a gift, and he said he didn't know what I liked, so you didn't like it if you bought it. Isn't that a waste of money? You don't know what you want, buy it yourself. This time it was like this: I went shopping with him and the children. I deliberately told my husband that my birthday is coming in a few days, so you can buy me a bag. Then I saw a bag I like, which happened to have no money on me. I asked him to buy it. He came and looked at it, saying it was not good-looking, the material was not good, and that I had no taste. I said, then help me choose one. He chose a style I don't like at all. So I don't want it. My husband said he went to the supermarket to buy things, and he was angry with me. What else does a 30-year-old woman want for her birthday? When I was in a hurry, I said go home, and my son and husband went to the supermarket. The more I thought about it on the road, the more angry I became, and my tears fell. I'm not afraid of your jokes. When we got married, it was simple. He gave me a platinum necklace (this necklace was strongly requested by my mother and my sister. My mother said there was nothing to commemorate the wedding. So I bought this necklace. I seldom wear this necklace, so I took it three times because I felt that he didn't really buy it. It feels like my husband doesn't love me anymore. In fact, I am an easily satisfied woman. I don't want him to buy me anything expensive. I like everything he gave me, because I love him so much. He has many shortcomings, such as bad breath, smelly feet, snoring every day, not washing his face and brushing his teeth at night, poor hearing, chronic pharyngitis and bad stomach. People may laugh at how I like him. This may be the so-called love. His greatest strengths are his sense of responsibility and kindness. Since buying a house, he feels like a different person. Maybe it's too stressful. There are still hundreds of thousands of mortgages outstanding, and business is not good again. Say I don't care about him. Actually, I care about him. Sometimes I really want a divorce and leave, but the two children are very poor. What should I do?
