Men!

[Weirdandwonderful1]

Why do men generally always think they're right?
My DH can say something one day then I can talk about said thing a few weeks later and he will absolutely deny he said what he said. Then if I try to give him evidence of what he said/did he will just act so fucking superior .
I know you'll all say just ignore it but it really infuriates me how he becomes all 'I am the master you're just the little wife'.
I don't see why I shouldn't have an opinion that is heard.
Anyone else feel this way??

Hm. I don't think it's men (though I've certainly encountered men that behave like this), it's the man that you are married to.
I'm interested that you think the advice would be to ignore it? I certainly couldn't. I guess it depends why he's doing it - does he genuinely believe that his opinion is 'better' than yours and that he is more important than you? If so I think you have a big issue.

I think you mean 'Man!'

You've married an arrogant knob. You chose him, as your main person to be around. You need to accept responsibility for that, rather than blaming half the species. It won't stop him being an arrogant knob, but it will help you to find a way out of your frustration with him.

Then tell it to someone who listens to you. And you need to listen to you. Were you raised in an atmosphere where your feelings went unheard? You've learned, at some point, that having a private/internal gripe is the natural outcome of not being listened to, rather than, for example, telling the person that they're an arrogant knob and removing them from your life, or removing yourself from their company as often as possible, or not bothering to tell them things any more because you recognise that it will just frustrate you.

Why did you marry him?

What kind of evidence? If it’s transcripts of conversations or recordings, I can see why he might act a bit funny.

Its not men, its a controlling tactic. He's putting you in your place. Now you've realised that's what he does, what are you going to do next?
Stop playing his game, change the script. Next time he tries it say something like 'I'm not playing your game. Treat me with respect' and walk away.
