While this may seem harsh, ultimately all these seem to me like lame excuses for lack of commitment and character.
I think we have to be careful, if we're blaming bad decisions on a person's 'bad character.' People in bad situations sometimes make bad decisions. But that doesn't make them bad people, lacking in character and commitment. And, frankly, the same goes for a H who neglects his W to the point where she's so desperate for love and connection that she ultimately feels like she has no resort but to look outside the M. This doesn't EITHER party bad people...just a people who don't yet know how to establish and maintain intimacy, communication and connection in a long-term, intimate relationship.
I cannot complain for not receiving from others, that which I've never asked them for.
