The view of marriage that most of us HD's has is and EASILY achievable reality for us. Heck most of us are there, we are waiting for the LD spouse to arrive. We have this idea of highly sexed and/or highly affectionate marriages. But for the LD spouse, they usually dismiss this as fantasy not the real world. To them NOBODY has this kind of marriage. They can not see themselves as being THIS sexual.
What I don't understand in all this, is why would anyone set their goals so low? You can be roomates(companions) or you can be lovers. Lovers is just a far better version of companions. So why not go for the gold instead of settling for the bronze?
