My aunt has started the process of taking guardianship of my dad to protect him from his wife. Nobody even knew they were married and the marriage is likely going to be annulled. He'll be better off away from that evil, manipulative and dangerious individual. Heck, maybe he will even get to see his grandkids before he dies.

I'm glad that your Aunt is looking out for your dad. It's awful when someone takes advantage of another person who is in need of love and support. I hope that everything works out for him.
