My boys deserve of my best effort, and eventually that means showing them a happy and healthy loving relationship with a "step-mom" so they can see how it's supposed to be......and model to them shared love in God, and prayer for each other daily
Good to remember, when you are having a bad day would you want someone to make it WORSE? Kids don't always know how to say what is bothering them. Be their savior NOT their problem or antagonist. They will value you for it.
