If these two weren't having an affair before her husband's death, I'll eat my hat.
Closing out bank accounts and other finances after a spouses death is wise and prudent if you have the mind to do it. Banks used to and some I say still do freeze accounts upon deaths. As for the time frame? Who are they to determine anyones elses grieving times? If she had waited 10 years someone would have had still an issue about it. I waited 6 months myself.
Being alone after a death of a spouse is indeed alone even being among family. Would you like some ketchup with that hat? I was lucky I started working at a new job when I met my present wife. No I would have never cheated on my first either. Strange as it seems some people who pray for a widower or widows happiness and comfort then are taking back when the prayer is answered.
With a 50% divorce rate and infidelity rampant in our society, you can be sure that many (not all) of these "victims" feel like they have won the lottery.
Greedy bloodsuckers.
