I am a 18 year old that has been friends with this guy for almost 12 years now. We have been dating for 4 years and we've had our ups and downs... but who doesn't? Is it possilbe for us to get married (just hypothetically) because I've heard the bestfriend thing doesn't work out.

oh thats not true at all its always good to start as friends!than go from there. so u no if there right for u. iv had and seen tons of peeps get married to the best guy/girl friend.

lots of best friends fall in love and get married, who knows you better than your best friend and loves you anyway? It happens many times and does work out.

It works out all the time so yes.

Of course there is nothing wrong with this situation and you would be mistaken to believe that your previous friendship has some kind of negative bearing on your current relationship. Your friendship has merely allowed you two to become comfortable with one another before you became intimately involved. You've been in each others' lives for almost 12 years now and therefore you have gone through many meaningful life experiences with this guy. I would argue that this fact only makes your relationship stronger. The "best friend" myth isn't real. If your relationship ever turns bad, it will be because of some other factor.
