I'm lying to my wife about my feelings from an affair
Why would you lie to her about the affair?
I am afraid of being honest.
Having an affair and not telling your wife is immoral. You should stop having an affair and tell your wife about what you have done.
I messed up. My wife is going to leave me with my new born baby.
I'm sorry to hear this, but that's why you shouldn't have had an affair and lie about it. I hope this is a learning experience for you.
