You've mentioned you don't see the point of romance, or the clinging together of in relationships.
Do you think it is possible, that part of this feeling you have, stems from the idea of, romance and modern relationships are, for lack of a better term, fakish?
Not sure if you like metaphors, but take for example:
John, goes to Walmart to by a new grill. He comes home sets it up, and then fills it with dirt and plants tomatoes. His neighbor sees it, and likewise all the neighbors catch on to this idea.
Years later, John Jr, jr, jr, jr, jr... Goes outside and sees the grill turned on it's side. He lifts it up, and examines the device. Comes across a dirty instruction set, and begins to follow it.
An hour later, the neighbors notice a smell in the air. They quickly go out to see what is filling their sense with such wonder. Then everyone empties their grill and starts cooking again.
Point is, I am just curious if there is a way in which you could envision this romance and sex in a different light, and if this metaphor has anything bearing?
