Hello Brokenmask94, welcome to PC! I hope you find your time here to be of benefit.

Wowza...that is quite the pickle to be in. Firstly, I'd tell your wife if she doesn't already know. She deserves to know and to be able to make the decision of whether or not she'd like to stay with you. Be prepared for a divorce because frankly, impregnating someone else is generally a deal breaker. Also be prepared to pay child support for this upcoming baby if she decides to keep it. I wish you the best, and hopefully this will deter you from making such a decision again.
