My brother wasn't talking to my father for the past 3 years. My father was a alchoholic who treated us terribly. I have 2 sisters who were named beneficiaries also. Plus my Dads girlfriend. I feel terrible. My brother is a wreck over it. But I also Have kids and he doesn't. He also has a great paying job. We live paycheck to paycheck.
