I would toss those magazines out. If he says anything just say "Oh, I thought you were done with them". You do realize that he's attempting to get under your skin by leaving these magazines around.
As for the grass seed, he doesn't know which end is up. What I think he's doing is cleaning up and putting things in order before he hits the road. A lot of them do that so that they don't feel guilty for walking out. They can say that they did everything they could around the home before they left.
I know everything is hitting your last nerve, but you've got to let this stuff go. You can't rationalize w/irrational people. There is truly no rhyme or reason for what he is doing. Don't allow him to take you down into the rabbit hole w/him.
Focus on you!
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.
