Online Only Relationships? I Think Not

I believe online only relationships are a big fat joke. First off, you don't even physically know the person. Second off, the person might be an impostor. Someone saying they are a different person to look more attractive. Then you watch the show "Catfish" and I think everyone on it is stupid. What did you expect was going to happen? I can pretty much predict the outcome most of the time. How can you say you're "in love" with someone you haven't met or even Skyped in some cases. I don't even feel bad for the people on the show who end up heartbroken after actually meeting the person. An online friendship is totally different. You're not telling the person you want to marry them, no attachments, just fine.
