You make a good point SassyRobot.
I am not slurring anyone here - it more from a global perspective that I have to agree. You see the same sort of thing that Sassy has mentioned from all over the age demographic.
Part of the problem, is that most males and females seem to neglect time to get comfortable in their own skin before making the jump into being with someone.
(Damnable biology - It would seem our need to breed still outstrips (no pun intended) our social want/need to relate to each other. That is to say, that we (in a global sense) still need some work in the social department as a critter)
How can anyone be a good partner to someone else, if they are constantly trying to define who they are, through their partner? Obviously, we all do this to a greater or lesser degree: Regardless, it makes sense that if you are good on your own, you will bring more security and stability into a relationship - That of course is not carved in stone, but I think there are greater odds of happiness.
