Well, I have a similar problem, except that I am dating my best friends ex boyfriend and we haven't confronted her. We live 30 miles apart and we love each other. We are going strong and have been together 3 and a half months and we love each other with all of our hearts. NO MATTER WHAT, JUST FOLLOW YOUR HEART AND IF YOUR HEART TELLS YOU TO STAY WITH HIM, STAY WITH HIM. NO MATTER WHAT, IF YOUR BEST FRIEND IS REALLY YOUR BEST FRIEND, THEY WILL UNDERSTAND THAT YOU TWO LOVE EACH OTHER AND WANT TO BE TOGETHER. NO MATTER WHAT, BEST FRIENDS WILL STICK WITH EACH OTHER AND NO MATTER WHAT THE CONSEQUENCES, YOUR BEST FRIEND WILL UNDERSTAND.
