Totally hear you OP.
I nearly start this very same thread on a weekly basis. My DH is a good and kind man. He has some traits which I find hard to love but don't we all.
But the combination of his less than good points plus the things he does which irritate me, often make me wish I lived alone.
For me it has definitely got worse with peri / menopause. But I don't think that is because I've suddenly become unreasonable due to my inferior women's hormones. I think it is because at this age and stage in life, I'm thoroughly sick of accommodating what is actually quite selfish and immature behaviour.
What is becoming difficult for me is that DH can see that I'm often in a stare of irritation and he (obviously) finds it hurtful and he doesn't understand why I'm so often like that.
I generally say things like I'm tired or had a difficult day at work but it no doubt feels to him as though I'm grumpy and moody most of the time.
I don't know what to do. I've tried (over the years) to explain to him that dumping greasy dishes into a basin of cold water / whistling loudly / leaving doors open on cold days / almost constantly playing loud music or podcasts / leaving the basin or shower dirty / etc / etc are annoying and selfish habits but he still does most of them.
At the moment I'm really struggling with what I call "making me do his thinking" where he will ask me questions about something I know no more than him about. I will repeat "I don't know / I'm not sure / you better check" with increasing irritation. He is then hurt and cross and doesn't understand why I'm being like that.
The other thing that is hard for me at the moment is that he has a tendency to relay information from podcasts or TV shows that he has found interesting. But he does it a lot with both me and the teenage DC. Plus he does it by sort of imitating the speaker rather than saying "he said / she said" so it becomes very mansplainy because he is kind of giving us a mini informative lecture as though they are his own words rather than saying "I heard this really interesting thing the other day". It's hard to explain but it is incredibly irritating.
So yes I feel your pain. I don't know what to do. Our kids will be leaving home soon and I'm worried about us being more and more on our own.
