OK, so come Feb. 23rd it will be 2 years since my mother left my dad. Out of the blue she blindsided him and left him a dear john note and took off to Kentucky. I won't get into how evil and cruel she is but here are the facts.

-They were married for 34 years before she left.
-All of us kids are grown up. (2 still live at home with my dad.)
-He had no idea there was any problems.
-She took half of the contents of their bank account.
-She has lied to get even more money from him under the guise of coming home.
-She sent him a letter stating he had two options. Give her 5,000 cash/$75.00 a week for 3 years/pay her car insurance for 3 years or Option B take him for everything.

I feel like a broken record trying to get him to go to a lawyer but part of him is holding onto the hope that she'll return and he is living under the idea that she'll get half no matter what. So my questions are...

-Will she get half?
-Will she still be entitled to his pension?
-Can he get her on abandonment even though he has sent her money? (Again because she "needed it to fix the car to come home" which turned out to be, of course, a lie.)
-Basically, is the horrible person who birthed me gonna walk away with what my dad worked so hard all his life for?

His biggest misconception is his pension. He seems to think regardless of what happens she gets half. But I was under the impression that it depends on the divorce agreement/reasons for divorce. I asked him that if I found information that was different from the misconception he is running on, would he go to a lawyer. He said yes so here I am. Any help would be greatly appreciated and thanks in advance. I just want my dad to move on with his life and enjoy his retirement.
