Is it wrong to avoid a parent who is trying to take advantage of you financially/involve you in a business you don't want to participate in?

My Dad’s a beligerent tyrant. He really has emotional problems. He’s always been that way. I love him dearly, but on top of that bad attitude he is now seemingly trying to involve me in his business. I have no interest in it. Furthermore, I suspect that he would try to take advantage of me financially if I ever let my guard down for a seccond, or even if I kept it up.

I don’t want to keep my distance, but I am not going to set myself up for injury o worse. Because of the way he acts there really can’t be any in between civility so I have decided to avoid him altogether. Is this wrong and disrepesctful, should I be more willing to accept any pain coming from my father before I write him off?
