three years, but I was always taught real love never dies, Us guys can be real jerks at time, but if there`s lack of affection after just three years well maybe its time to go.
Some day we will all hopefully grow old and grey and well if the guy cant even walk down the street and hold your hand and smile at the same time because he cant help but show how happy you make him feel, well perhaps it isnt worth it
What ever you decide put up a good fight first so you can at least know you tried if it dosent work out.
