Married Divorced Married again

Years ago, I was on a trip with a group of friends and one night we were drinking heavily, and it was a blur to my mind. I awoke in bed with a female friend from the group and took it as I'd got lucky. Later on, we both were at a loss to what happen the night before. Then finding a marriage certificate in my pocket, shocked both of us. We quietly got divorced as we weren't ready for marriage at that time we thought. But stayed good friends and started dating off and on and 18months later we married again with our families in attendance and now we've 6 children and looking back said we should've divorced the first marriage. But were in shock that we married while drunk and didn't look at the possibilities of what could be.
