We got married 10 years and 7 mths after we met, and we didn't 'co-habit' properly until 5 months before the wedding! Prior to that I swapped between living with my Mum, living with him at his Mum's and living with a friend.
We're coming up for our 8th wedding anniversary.
We were both rebelling in our own ways. My parents got married 6 weeks after they met, and had a turbulant marriage which dragged on too long and ended in divorce. My DH came from a background where he felt pressured into 'work, wife and family' and he resisted it for as long as he could!
