I don't know if I'm the old man of the group, but this year marks 40 years since my wife and I first dated in our Junior year of high school. Briefly broke up after graduation when I went into the USAF, but got back together shortly after I came back home, and will be married 32 years this May.
It's all about give and take, understanding, and not staying angry. We've had our ups and downs and screaming matches, but always made peace by the end of the day.
There's no listing of who does what chores, although I always take care of all outside stuff, she does more cleaning than me due to our schedules. Things have changed over the years, I used to get home from work first so I always cooked, which I love to do, BTW. Now I work a second job some nights so she cooks more on weeknights.
We have some shared interests, musically she's gone with me to see some shows, but isn't into the heavier stuff, so DT, Priest, Maiden, etc. shows I go with a buddy or two; Country music, she'll go with our daughter and/or some girlfriends.
She has a monthly book club clique with her girls that is more about having some wine than talking about the book, she also has a movie night, and goes to happy hour once a month or so with the girls from work. I like to tool around in my garage on weekends, light the grill or smoker, crank the tunes and drink some beers, occasionally have a buddy over and light the chiminea on a Friday or Saturday night. We'll also get together with other couples a couple times a month, go out to dinner, then have a game night or play some cards after.
It's a delicate balance, but it works. And when in doubt, just shut up, she's right, I'm wrong.
I wear the pants in my family, and i have her permission to say so!
