I don't think this is a good idea. Firstly, they are dating online and have never met. That may work for adults sometimes (I don't really get online dating. I don't think it works, but whatever. Do what you will.), but I really doubt it will work for teenagers. Second, they are four years apart. Once again, that is okay when you are adults, but as a teenager four years is the difference between second grade and sixth grade. It just seems like too much of an age gap.
