Me and DH have been together for nearly 40 years, and married for nearly 35. Very happy and couldn't imagine life without him. He is a PITA occasionally and gets on my nerves! But I am a PITA too and get on his nerves occasionally. He gets on mine when he won't stop talking and follows me around when I am busy doing stuff, and I get on his because I am a bit messy and untidy!
We have had rocky patches and wonderful times. Travelled a lot (30 countries or so,) raised 2 bloody perfect daughters, lived in 7 different homes, had 7 jobs and 5 redundancies between us, gone from being solvent to piss-poor, and then back again, and lost all 4 parents (both quite young we were too.)
We went through a fruitful youth where we spent like money was going out of fashion, travelled extensively to 3 different continents, spent our late 30s and 40s brassick, and are fairly comfortable again in our 50s, helped by the fact we have lived in a very cheap social housing property out in the sticks for the past 10 years.
When DH was away on courses at work (when the kids were at home and I worked 3 days a week,) it was great to have a few DH-free days, and just me and the girls, and I had work colleagues to chat to, and it was lovely to have DH back!
But the girls have left now - a decade ago almost, and I have been working from home for 2 years (coz of covid,) and when DH went away for 3 days in October last year, I was REALLY lonely. 
Our DD are 22-25 miles away, my extended family is even further away, I have no work colleagues as I WFH, and even though people are friendly in this village, everyone was very distant (physically) during the pandemic, (and still are to be honest.) So I felt very lonely. I had the cat, but she was asleep most of the time! 🐈
But yeah, tl;dr, I am truly happy and can't imagine life without him now. We have lots of good times and giggles and cuddles, (sorry, cheese alert!) it's great to have someone to chat to about our day, and someone to rant to when we're angry or down about something. And it's great to know he's always there to fight my corner (and I am there to fight his.) As I said, there have been rocky patches and tough times, but I have a lot of happy memories with him, and I love him very much...
