moving and thoughts

So, my daughter who hated her room, now wants her room back. You would say well Lacey give her, her room back. Not that easy...Meagan lives with us. I love Meagan and actually I have really no complaints about having her live her. She is a sweet girl. But now Riley is full of tears wanting her room back. I don't want to ask her to leave because well 1. where would she go, and 2. the money has been a big help. With Riley in school and other things, I just don't know what to do. So, I think and pray what do i do. I want to make my daughter happy. But on the other hand, i want to make Megan and my financial situation happy. I keep hoping I will hear God say one answer or another. My daughter is my world. And I want her to be happy. I really do. But, I also want to bless Meagan, and stuff. What a predicament im in.
