OMG I know this sounds super cheesy, but I have found my people too! (Mid 50s here...) last period 3 years ago... So well into menopause.
My DH gets on my last bloody nerve SO much some days. Some days he doesn't, and we have some good days and a good laugh, and we have stuff in common, but he pisses me off and annoys me at least a third of the waking hours we are together.
I work largely from home, and he has cut his hours down to just 3 ten-hour night shifts in a row, (with 4 days in a row off!) and he is at home SO MUCH that it makes my blood boil! The kids have left home, and he seems to want to be at home all the time, and wants me to go everywhere with him, and chats incessantly when we are at home together!!!
Funnily enough, he wasn't so keen to be at home all the time when the kids were little/younger/living at home! 
The way he eats irks me, the way chucks out a long massive BELCH after a fizzy drink makes me feel stabby, the way he follows me from room to room annoys me, the way he can't go two fucking minutes without chatting shit about fuckall, (or just stuff I am not interested in) pisses me off, and his taking over the TV and putting crap on from the 1970s and 1980s fucks me off too!
Thank GOD I have the internet/mumsnet, and bloody netflix and catch up on demand on my laptop. I would go utterly nuts if I didn't have that, and I had to just tolerate the shit he wants to watch, and listen to him prattling on about fuck knows what some days!!! Seriously, he puts some wanky 70s sitcom on (and I try and watch something on netflix with my headphones on,) and he still tries to cunting talk to me. ARGH!! 
We have had separate bedrooms for 10 years (I could not sleep coz of his snoring and got used to it and would never go back,) and we haven't had sex in 8 or 9 years (since our mid 40s...) He went off it first, and then I caught up about half a year later, and I never want it again, and don't miss it even slightly.
He has suggested it a couple of times about 5 years ago, but I just flatly said 'nope, I am done with sex. Not for me again, ever.' He doesn't seem too bothered, and we are affectionate and get on OK in general, but yep, like many women on here, I feel my heart sink when I think I am getting a cosy morning to myself and he fucking gets up. I can hear him opening his bedroom door and I think 'FUCK THE FUCK OFF! Give me just a couple of bastard HOURS to myself PLEASE!!!'
I also fantasise about him leaving so I can just be on my own, do what I want, when I want, and not have him trailing around after me like a fucking shadow!
Oh, and I dislike going out to the shops with him too....
He either has a snappy and arsey attitude with shop assistants and waitresses etc, and is rude if people get in his way, or are walking slow!
OR .....
he tries to be funny and jovial with every fucking female he encounters. It makes me cringe because I know these women have to tolerate dozens of ludicrous middle aged (and old) men trying to be funny, ALL DAY. He thinks he is clever, funny, and unique. They think he is a cunt. So do I.
AND he gives me an evil glare if I share banter with a man (and it is very rare I do!)
Ahhhh, that felt good! 
I have felt like this about DH for about 10 years by the way! Pretty much since our two kids left home. Probably just didn't notice it when they were at home as I was busy with them....
