My wife and I agreed that we weren't ready to have kids, but she went off birth control without telling me and now she's pregnant. I feel so angry and betrayed right now. I have thought about leaving her, but the thought of leaving a pregnant woman just doesn't sit well with me. But I don't know how I can trust her again, let alone raise a kid with her. What now?

I would hope that you two can talk about it and resolve things -- agree with Albert and ask her the deeper reason why she did that. If it's something you can live with, then the best thing is really for you two to stay together for your child. If you can't ever forgive her or trust her again though, I don't think there's anything wrong with raising the child separately. It's best for a child to have a mom and dad but it's really not if mom and dad are always fighting and the home is unhappy. Good luck.
