I'm just pointing out the level in which the relationship can evolve into.
In which there's a extremely slim chance of there being any future between the two. A smaller chance than local dating provides, because there's the 'distance' and 'lack of physical contact' factors. I'm not just talking about sticking it in his/her pooper. When all you feel (physically) is a heart beating, the material of your chair/desk, and your fingers bouncing around on your keyboard, in a relationship, you begin to desire more and more real physical attention. Lack of causes some mental stress.
In conclusion, a long distance relationship (online dating) will only go anywhere if you have patience, a strong will, and enough money to actually go far permanently. And most of all, experience, in many things required.
