First year of marriage :). I have been married for 13 years to my soul mate. However, that first year was sheer bliss. No jobs (got married at 20 - both in college) and just had a smashing good time. We lived on a chunk of land, out in the country in Arkansas, that was just down the road from his parents place. My husband and I built a small cottage to live on and his dad financed it. No rent, hardly any bills.
My family was close too. We were young, in "puppy" love, with our rose colored glasses still pushed up on the bridge of our nose. It was a magical time before there were any worries. However, this year ranks high as well ;).
