Dear Prudence,
My husband and I got married nine years ago. Two years after that, his parents died in an accident and it was terrible. We were both in our early 30s, but the problem was his parents left behind his 10-year-old sister, Beth. She came to live with us, and we have housed, clothed, and fed her, paid for her therapy, and provided emotional support for her. She’s a great kid, I love her, and she helps babysit our children. However, we live in a cramped space and my husband and I have always wanted to expand our own family. I want to send Beth to live with her grandparents next year to free up some space. They couldn’t care for her when she was younger but should be able to now that she mostly fends for herself. She will be in college and will only be living with them on breaks. I brought this up to my husband, and he was outraged, saying that Beth can live with us for as long as she wants. I feel I was really good about taking Beth in when we were still practically newlyweds, but as much as I love her I don’t want her living with us forever. Am I being unreasonable here? How do I continue to approach this topic with him?
