In any case, we seem to have a habit of trying to generalise the nature of relationships - online or off. We are probably forgetting that people are individuals, and that while with a particular person a relationship might feel too fast, it might feel too slow with another. I think the success of transferring online relationships into 'real life' depends on much more than whether the online conversations felt real and true to each person's personalities. Putting it bluntly, you have to be able to be comfortable with the other person's real life habits and mannerisms, all of which you have no means of experiencing over an online situation. For example, you may think that the other person thinks the same as you do, but whether they would leave the dirty dishes in the sink when you prefer to have a sparkling clean kitchen, remains to be seen.
Passion is, again, something else.
I've been thinking a lot about relationships lately - as usual. I've come to the conclusion that the online thing is not so different from the offline one. It's mainly a question of emphasis on different aspects. I'm convinced that the way to a fulfilling relationship rests in taking things slowly. Nowadays, people tend to rush into relationship, intimacy, engagement.
