It's just so draining having those circular (pointless) 'discussions'. Physically, mentally, emotionally.
I just got quieter and quieter. He would then accuse me of not being open enough with him, not wanting to 'discuss' anything... but what's the point if everything you say is just dissected, analysed and you are told in detail why you are wrong. About even the smallest things like which bloody cat food to pick.
Now I feed my cat the food he (the cat) likes the best.
Now I'm in a relationship with a lovely lovely sweetheart of a man who actually understands what a discussion really is. It's not you red, it's him. He won't change because he doesn't think he's wrong. He'll never ever change. It's all output and no input. Control. Blame. Instruction. Lecturing.
I guess I just forgot over time what relationships were supposed to be IFSWIM? Support, love, caring, respect, laughter, fun....
You have maybe 80 spins around the sun on this earth. Don't waste any more of them with someone who instead of enriching your life does the opposite.
