Sorry to hear about this. I've been there, and I wouldn't wish this on anyone. First off, regardless of any laws or religious rules, a marriage requires two people to continue. If she wanted out, then there's nothing you could have done. You can't keep a marriage going by yourself when the other person wants out. So at the very least, clear your mind of any guilt in that regard. Sin requires a choice, and in this matter you didn't have a choice.
In regards to divorce itself, you could talk with your priest or pastor. There's a lot of different Christian thought about this, and best to stick with someone you trust.
Past that, take time to grieve. A lot of time. Your marriage and your future just died. Your life will never be the same. Take plenty of time to get used to living alone, any situation with kids, untangling finances and all the rest. Take some time trying to figure out your relationship with your former in-laws. Some want to still be family, others will want to break contact, and your feelings are going to be complicated. Don't rush into another relationship. Your emotions are going to be very unpredictable, and it's not really fair to whoever you meet.
