Detach a bit more....one of the things that the MLCer can't stand is for us to continue being nice to them when they are being such brats. They attempt to push our buttons one minute, hoping to get us to react and then later they are nice. It's a dance of patience. Continue to be nice and pleasant to him. Eventually the fire of anger will burn out.
You may never know or understand why he is hates you. Why? Because he really doesn't know himself. He most likely hates himself right about now and is projecting on to you. I know it's tough not to hurt from this stuff, but you will need to find a way to allow it to roll off your back.
Dig deeper for more patience.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
