I doubt his friends know the "full story".
And there is the problem of them not being disinterested parties as we are, not having the same amount of different experience as the members of the forum do, and not having the experience in years that we have.
I have no problem with seeking relationship advice in a forum. In the end it's just information for one to add to their own intuition and judgement. I can't see anything wrong with that.
I agree with citizenzen, we are all members of the macrumors community, and most of us are interested in contributing to this community. I am twice as old as the original poster, and may have useful advice for him.
I don't see a reason to "criticize" the original poster for being young either.
