My husband and I were married last year, and we are loved and accepted by all in-laws and extended families. My mother-in-law and I have a great relationship, and love spending time together. My brother in-law is a few years older than my husband, a confirmed bachelor, and very happy with his life. While visiting him a few weeks ago, I noticed what horrible shape his 1 set of sheets were in, and he needs a blanket and new pillows. So I decided to buy some new things for him. In chatting with my mother-in-law, she said she planned to buy him a new mattress this year, and was going to spruce up the bedding too. I got the sense that she was a little hurt that I was trying to take care of him, in a fashion, when she had been doing it for so long. Maybe I should have talked to her before buying these things for him? We have always been great at coordinating gifts and communicating about my husband, it never occurred to me that doing something nice for her other son would hurt her!
