I totally agree with your initial assessment of failed relationships. It is often because people don't really get to know their partners well. My only qualm is it seems these days that even if you date for a year, or three; people will switch up on you. That person that you grew to love and admire turns out to be someone that you can't see spending a lifetime with.

It's so much more difficult and complicated than it should be. Not sure if there is a workable solution. Good list to ponder for either sex. Thanks.
