As for myself, my wife and I married at 20 and 25, and it'll be 10 years this June. We have a girl, 4, and a boy, 2 this April. We have a 4-bedroom home with a large backyard, a car, minivan, and motorhome. We are both elementary school teachers (she started a few years after I did). We met in college, and I was smitten with her from the day I saw her - though we didn't date until a few months later. I had a live-in girlfriend in my apartment with 2 other guys at the time, and I was too embarrased to ask her out anyways (though I walked her to class every day.)
We tend to agree on most things, with a few reasonable differences here and there. Despite us both being Leos (she's July 23, I'm July 27, my older sister is July 26, my father-in-law is July 29), we rarely have fights, and even then, it's over quickly and we cool off for a few hours to a day.
She knows I'm a geek, but I'm good at fixing stuff, and I do my fair share of household chores. We've really become homebodies, and would like to go out and do more, but we had kids later than all of our friends - and our best friends have moved out of state. Not that we mind sitting home with the kids and watching TIVO, but we're looking forward to using the camper more when our little boy is up for long trips.
We like our married life. It's been very good to us.
