After my 1st wife died, I figured I was too young to be a lonely old man (59). I got on a Christian online dating site to see how it worked. After entering my profile, it was less than 2 hours before I got an email from a gal 700 miles away. It worked. We had our 11th last week.
The Christian dating sites are by no means a guarantee that no predators or con artists will be on it, but it does up the odds of finding someone real. It's always 'buyer beware'.
