I saved our marriage but the resentment is still there.
YOU saved your marriage? All by your lonesome? She didn't leave either. It sounds to me like you see yourself as the hero here. I guess what it comes down to is this: Do you need to be right more than you want to be happy?
I've been married 23 years. The early years were rocky. I spent quite some time feeling awfully self-righteous about being the good one, the one who was right, the one who magnanimously forgave the sinner! Every time he annoyed me, I remembered and rehearsed every single instance of wrongdoing. Spending time in The Word is the best cure for this type of attitude. I'd bet everything she has done to you, you have done to God.
My husband is awesome and we are pretty doggone happy- wouldn't trade him for the world! But it takes time, it takes work, and sometimes it takes a lot of humility. But it's worth it.
