Loneliness and aloneness.

I just read one intresting article. About difference between loneliness and aloneness. It's saying that people feel lonely because of their exceptions. They feel lonely, when they have not enough friends, not that much how they want to. Because their friend(friends) is(are) not that close to them as they want to. I've never thought about it, but it seems correct, this theory works with me. It is the same about feelings of beeing loved or loveless, that comes because of one exsact person. One exsact person. All the time. Is it selfish to want one man only for yourself? Only for yourself and nobody else in the whole world. One persone to be yours. To be the closest to him, him to be the closest to you. You and him in your own university. And noone is matter, never will since you have each other. My dream. Can I hope that it will come true? Or is it just a sweet fairytale? Am I too old to believe in fairytales?
