Anonymous family confession

I love my daughter. I just dont love her the way I love my son and I know it. I think shes starting to know it too. Shes 7. She wants to be on me all the time and I get this tight feeling in my chest like I need space. With my son I never felt that once. He could crawl all over me for hours. So I buy her more stuff than him. My husband says I spoil her. idk what else to do
