In a Marriage why do some men have to always be right?

My spouse seems to always want to be right about everything ! If i don't agree he acts mad. It can be over something thats not important too. Just little things but He is getting on my nerves lately! He doesn't listen to what I gotta say about it. or i try to explain it but he don't seem to hear it? He only hears what he is saying it seems. I feel like he is getting mad at me over nothing really. this has happened a couple times hear lately. so i wonder whats wrong with him? we been married 16 yrs and now I ask myself today how did we do it? this sounds crazy to me to. or how did I do it this long put up with him?! why does the small stuff make him mad? like keeping a door shut so the cold won't come through it , i try to say i will close it soon as I get done in there but he doesn't listen and gets mad. see our house is cold right now and we have to close some doors to other rooms we're not using in order to keep the house warm . its always like that in the winter when its real cold outside. for some reason our central heat doesn't work well when the temps drop low out. so we use other heaters through out the house and close some doors. I was going in a room and he kept talking about keeping the door shut and i was trying to say i will close it when i am done in there. but he didnt' listen he flew off mad took the heater with him and went into our bedroom and shut the door! see how stupid it is. he gets mad and then he makes me mad , real mad! so i let it all out ! Maybe I should start ignoring him next time? what do you think? I dont know why I allow him to make me so mad when he acts like that. I ask myself how did i do it before. I guess i let him be the boss or have his way. or ignore him. who knows.
