Be warned, i am going to be blunt and it might sting –

Nope, its not real until you actually meet him in person- the internet can never compensate for meeting the person in real life – ask anyone in long-distance relationships for instance. I think you are focusing way too much on this person whom you think you know. And jeez, leave your house – talk to people around you, be involved – you cant live your days in front of a computer and miss out on whats going on outside your window. Clinging onto to this connection and ignoring other potential ones is a sign that you need to re-evaluate things and find balance. There is nothing wrong with you but you need to get a life outside the computer.
