Dh and I. Together 17 years and married 14.
My parents, quite disastrously, were together about 14 and married for 12 (separated for 2 of those years).
Fortunately, I have a much healthier sense of self worth and better relationship skills than my mum. All of her relationships have been with complete losers, even her 2nd marriage, which has lasted 20 years. I learned a lot from her about what NOT to look for in a man!
