My father had an accident, doing electrical work for Amtrack. His back got hurt really bad, and he received a settlement or some shit. Somehow he became unemployed. I'm forgetting the specific details. Anyway, I believe that killed the sexual relationship. I remember them having fights in the following months after it occurred. Although they tried to shield us from their fights. He basically wouldn't get a job/might not have been able to work. I remember after he finally moved out from our new house that he started working for Tyson (whatever the chicken meat packing company is). He took a fair amount of sick days for his back or something and was laid off. So his back issues probably were legit.
Sorry rkd...don't know how I missed this.
Yep...he was no longer the man your mom married...and it's sad, because marriage vows specifically say, "in sickness and in health".
EVERYTHING in life is conditional...
EVERYTHING. 
I just came across this, bingo man, that's why you can never love a woman, because they don't love you for you, like Kidd said, everything is conditional. Even the most devoted woman will drop you if something happens (Even if it's not your fault) and you lose the value that they are with you for. That goes for guy friends as well.
