Am I on the right track?

"I only need to forgive her for the A, and I will if she will come home. "

This shows you're not willing to change. You're still score keeping. You will only forgive her IF she comes home. Forgiveness is something you give with no strings attached. Either you forgive or you don't.

"MrBond is right about my always having to be right. I can work on that, too."

You're still wanting to be "right". And either you WILL work on it or WON'T. There is no "can".
