IMO, Bob went missing to save the money.... Sadly Bobs future after his first wife passed was non existent when it came to those offspring who shared his dna..... Momma was gone and Daddy lived a bit too long...
Their online activites liken to those who wish their parents died within weeks of each other. It's a shame Bobs offspring never got to the point Daddy was no longer responsible for his half century year old off spring... He more than gave... but sadly, it just was too much when Bobby decided after his 50 plus years of til death do us part, he might be blessed to have last bit of his own life.
No, IMO, after supporting 3 generations- there was simply no room left for Bob to have any life after he honored his marriage vows... These kids thought when one parent passed the other would shortly there after....
and Bob, If nothing else, some of us know you fulfilled you duty to your wife, to your country to your children..... Sadly, imo, you lost your life - because you thought - like most of us do, once a spouse passes on it is your God given right to marry another.... I'm so sorry the evidence does not point to your children seeing things that way.
God Bless you Bob... you are not, nor will you be forgotten.
