I just saw this post now. I am so sorry for what you are going through.
I hope you and your father can find a solution to the existing issues.
I know it can be difficult working with relatives, especially parents. I had to work with my dad for 7 years and it was not easy. The only difference, believe it or not, is that at the time, he worked for me. He slacked on his job and expected me to cover for him with the big boss. This made me very unconfortable and upset. I was happy the day he retired and I didn't have to put up with that crap any more. I have since moved away, as you know, and am in a new job.
I truly don't know what to tell you since it's a family business.
I just hope you can resolve some of the problems with your meeting with him.

Don't worry to much about it either way....
I live by the philosophy that when a door closes a BIGGER and BETTER one opens. You and your critters will be fine.
PM me if you need.
