My 10 year old stepdaughter wont stop wearing my 9 year old daughter clothes. This bothers me because the 10 year old will wear them back to her mom house and I will never see them again. This has been an ongoing situation for the last 4 years. It seem all her clothes and my daughters clothes end up and the other house. Then when I ask her mom to send clothes back she says she doesn't have any. I just want to scream...

So over the past 4 months I've bought my stepdaughter around 6 pairs of new shorts. the other day she tried to wear a pair of my daughters shorts to school and I said no and put them away. Mind you she had clean shorts in her dresser. This made her angry and cop an attitude with in return cause me and my husband to get into a big argument. He says I treat my daughter different than the other two girls. He's right, I do. I love his daughters but they act differently than my daughter does. They yell, talk back and my daughter doesn't. She listens to me and my husband. I ready to throw in the towel. Am I overacting about the clothes? Please help
