Together 4 years when we got engaged, and then another 3 before getting married! Not the most impetuous you could say
We were together just over 5 years and he popped the question in march last year. We are together just over 6 years now and living together for 2. I think it depends on age and how well you think you know each other.
We'll be together 9 years this valentines day... he popped the question last November and we're getting married this September. So we'll be married before it hits the 10 yr mark... he took his time eh!!
