Based on this logic thousands if not millions of people who had met people and fallen in love by letters for centuries did not have real relationships too. Or most people in the military would not have real relationships either based on that definition since most people on active duty spend at least as much time in far off places keeping in touch by phone and email. My mom once told me that when we were growing up she was effectively a single parent but that does make make their marriage any less real. Also you should consider that studies have been done that show that in our current society literally everyone spends on average more hours on a computer then they do in the "real world".

I think that this is generally true. However, I do think it is possible to meet someone online. I think that if it is an actual relationship, plans should be made to make it an irl relationship, or it is doomed to fail. I'm not sure seeking online relationships is ever the best idea, but sometimes things happen even when you aren't looking.
