He was convinced by his daughter and his son that he wasn't happy here and that my mom was controlling his life. There were some trust issues in the past, he used to be a heavy drug addict, especially to heroin. He beat that several years ago and stayed clean, but recently he got back into the practice of smoking pot.
I don't criminalize pot smokers, it's not my job. I don't think it's morally or socially wrong but when you make a promise to someone to stay clean, I think you should expect that person to get royally pissed when you break it and start lighting up.
Because of that, though it happened several months ago, the rift of trust has deepened and he never did anything to really try and repair it. He never spoke up, would keep things to himself. This weekend when my mom was away with my other sister, he was gone most the weekend. The excuses he kept giving me for leaving were bullshit, I could tell. Who goes for ice cream at 9pm at their other step-daughter's place (he has a lot of kids) and doesn't come home until 9am the next morning?
When mom returned home, the truth came out. He had been planning on moving in with his step-son. He had already made a damage deposit on a place.
He's gone right now. I'm gonna miss him and I do love him. He was a much better father than my own. Makes it hard to believe that he wouldn't see where he was going and is in a worse place now.
