hi kittymammas and WELCOME to SR! This is an awesome place to be for Experience Strength and Support (ESH). I'm glad you're here.
I think it's wonderful that you're beginning a new chapter of your life, for yourself and your children. I know there are feelings of guilt at play (I had them too), but try to gently remind yourself that you are creating a safe and loving environment for your children to grow up in. That's priceless.
