Hello & welcome to the forum!
You cannot change him. He probably doesn't realize he's doing it. Or if he does admit to some negativity, he justifies it by saying he's just "being realistic" or "being honest". He's happy being grumpy and dissatisfied.
Better to focus on yourself. Accept him for the grumpy person he is. Get good at tuning him out. Or get good at scheduling it so you're never home when he is.
