Is OTHER wrong in the post ? POST : Background: my stepmother came into my life when I was about 5 or 6. I am the youngest of five children but the oldest three went with my biological mother. I grew up at odds with my stepmother and sister who generally teamed up on me as my father was working on the road 8-10 months/year. 

Fast forward to last year: 

Dad had been having a lot of health problems and appeared to be on his death bed. I was taking sick time off just to be with him. He'd go to bed and I'd have a couple drinks to blow off some steam before heading home (90 minute commute). I even cancelled a family trip to China that my wife planned to be by him (lost 1000s in flight and booking fees). Stepmom accuses me of using dad as an excuse to drink. I blow it off. 

Chirstmas comes. She asks what my son wants. "A nice RC car." She goes to Big Lots and the damn thing won't turn straight outta the box. Wife gets a super-used silver plated watch with chinks of silver missing everywhere disguised in a new box. Wife and son are upset but I tell them to be grateful. Nothing was said to stepmom. While visiting one day, she takes me aside, stares me right in the face, and accuses me of cheating on my wife. I never have. I blow it off.
 
Valentine's Day comes and I wish her a happy Ash Wednesday (she is Christian, I am not). She responds by saying she hopes I have something nice planned for my wife. I say we're going to a nice restaurant she wanted to go to. "That's a bad idea. It'll be long waits and terrible service." So I go off on her. No cursing, no name calling, but I brought her to justice on her previous offenses. Her reaction? "We're making a lot of important decisions right now and you just made them easier." Wow. Using my dad's poor health to threaten to take me out of the will (they have a very healthy retirement). 

I stopped talking to her. She and my sister stopped talking to us. Come to find out a couple months ago, she went to the hospital for jaundice. Dad is forbidden by her from telling me about her condition but she took a dozen people down to the Bahamas last week so it's probably pretty bad. Also, some of dad's comments lead me to believe she doesn't have long.

I couldn't be happier. My life has been relatively drama free since I cut her out. I am looking forward to spending my dad's last year or two without her in the picture. Not to mention, I think it's just desserts that she used my dad dying against me and now it seems she will go first. AITA here?
