Thank you all again for everything. I know this is going to be an uphill battle, but I truly believe God placed her in my life for a reason. I love her unconditionally, and because of that, I have to forgive her. I still believe in my heart that biologically, the baby is mine, and that if anything, this is a test of my faith, and the devil trying to attack my marriage. And, I'm not willing to give up on her, or our family. I have faith that when the baby comes, everything is going to work out great.
God bless you! You are a good man.
I hope she has a repentant heart and I would suggest that counseling is needed to find out why she did this to you and to help her to see that she cannot do it again, ever. As a new mother she needs to put her family first (you and the baby) and forsake all other relationships that pull her away from you and this child. Is she Christian? God's word tells older women to teach the younger women how to be good wives and mothers. I hope that you are active in a friendly, Bible believing church where this can happen for her and that whoever she is hanging out with that might have a worldly, licentious influence on her is removed from your lives (in Jesus' name!).
You sound very excited to be a father and your level of commitment to your wife is not something seen in so many relationships. I will pray for you!
