 Yeah, I mean, have the boundaries. Honor him, be kind to him, take good care of him. Don't believe what he says. Don't buy into his version of reality. If he criticizes you, he tries to manipulate you or whatever he's trying to do, just don't buy into it. You just got to tune that out. Take good care of him, visit him, make him a pie, do whatever nice things you do for him. Just don't internalize any of his manipulative approach.
