Is it common for widow(er)s to compare new dates to their former spouse?
I would consider myself a decent Christian woman who loves the Lord, so surely there could be decent Christian men on there as well, but not all of them are. Give them whatever information you have just in case.
Pro: There are great people online (I have found them, know them, and am one of them).
Pro: For someone immersed in a career or ministry, online dating can open up opportunities that normally would not exist. There is no “Well, I plan on dating someone for six years while I finish my Star Wars collection (sorry, guys), master the art of cooking Ramen, and move out of my mom’s basement; then, maybe I will consider marriage.” For the most part, the people on dating sites want to be married—soon. However, for every good, godly guy online, there is a bad one.
Being cautious can go a long way in preventing injury. A friend of mine shared a story from one of her previous churches. Use a screen name that you do not use elsewhere (IM, Facebook, bank account, etc).
For those considering online dating, I have this advice to help curb some of the risk. Do not (I repeat: do not) go into this in some Jonah-like attempt to wiggle your way out of where God has you right now. The church had a significant singles ministry and many were involved in online dating.
