Is OTHER wrong in the post ? POST : My parents are in the middle of a divorce because of some serious illegal activities performed by my dad. We found out in October. 

I have been working as a contractor for the company my dad works for. Dad is going through legal things right now but it was a good part-time position so I kept working there. For the last month I've been spiralling into a depression and he knows that. So about 3 weeks ago I told him that they needed to find someone to replace me because I'm going to be done working for them. I needed space from him because I'm only allowed to talk to him about work and it was getting stressful. (Something to do with his therapy process)

In all honesty I was going to stop working for them around last week but then he said he found someone to hire and I didn't mind being the one to train new guy since I know I'm the only one that knows what I do.

 Dad said right away so I waited. And waited. I confronted him this morning about it and he said that he wouldn't start for 2 weeks and that they expected me to stay till new guy starts. I told him that I'm not comfortable with that and that I'm going to be done working for them as of now. 

For him that meant that I don't have contact anymore (personal because of above issues). And that I didn't give him a timely notice. 

I think he is frustrated because he won't be allowed to talk to me anymore after this and he thinks I hate him (not true, I am disappointed). I don't think he actually cares about the job. 

I feel like asking him 3 weeks ago to replace me was plenty notice. So AITA?

Side note: I don't want to talk about the divorce. Or why they're getting a divorce.
