I kind of understand what you're saying and think you make some valid points but I can't help that think that most marriages wither because both spouses get so busy taking care of the house, the kids, finances,(or lack of) their jobs and almost everything and everyone else that they forget to take care of the one person they vowed to "love, honor and cherish." We take each other for granted and think that "our" time will come but the years keep cranking over and "our" time keeps getting pushed aside.
Hindsight being 20/20 I see what happened and am so sorry for my part in allowing my marriage to get to the stage where my husband has come to believe that he doesn't love me anymore. I mean, yes, he's going through MLC, and yes, he's lost his mind, but at the same time I have to ask myself if I did everything in my power to make our marriage a place that he would never want to leave. Hell, a good part of the time, I wanted to run away.
