So true, that's why the saying goes, "Hard times will always reveal your true friends(and family)"when you need them the most they desert you. I would never do that to someone, it's just common sense they will need your support.........and yes, the marriage is usually over by the time the "paperwork" is started, doesn't deteriorate overnight.
I have always said that I could count my true friends on one hand and that includes family, I think that holds true for most everyone. After getting divorced and those two friends not contacting me, I can now count my true friends on 2 fingers. Funny thing is they are both my oldest friends, we've known each other since 3rd grade, still talk regularly and would do anything for each other. I have no family members that I consider true friends, I've been stabbed in the back by family more than strangers. The few family members I had that I did love and trust have passed.
