For me personally, I think you shouldn't force yourself to try and tolerate him because of what he wants. He doesn't sound like someone actually "desperate" to hold onto your parent/child relationship. His actions don't really show that, and if he did want to keep that connection, he would at least try.
I dunno...from my experience, my family haven't been too shy about cutting people off, regardless of blood relations. I know my mom did when a few cousins didn't care for their mother (her great aunt), and I know I did when a cousin tried to verbally abuse me (I lived in the same house as her for several years) because of her own mishaps.
I'd say that, for those few days, it might be wise to keep minimum contact with him. If he doesn't want to change a bit of himself in effort to keep that relationship, he's probably not as desperate as he claims to be. Course, I can't speak for your father and you (because you know him better than I do), but I just feel it's unhealthy for you.
You shouldn't have to endure this. If you're living a successful life (and success can mean many things) and you're happy, that's something a parent should want for you.
