Since my marriage is ending..would this be a good idea?

I would and have. As long as your baby girl has a safe place to stay while you're gone; I know it will be hard on you but she's young enough now that she will Probably just think she's visiting who ever she'll be staying with. Sometimes being a single mom is about sacrifices that we don't want to do but know that we need to. Just make sure you trust and she loves who ever she'll be with. I have faith that you'll make the right decision. Good Luck and God Bless you for anting to help and make a difference.
