"There comes a point in your life when you realize who matters, who never did, who won't anymore, and who always will. And in the end you learn who is fake, who is true and who would risk it all for you."
Yeap. What it comes down to is your actions in the end. As the saying goes actions speak louder than words. We can make careful plans if needed to to end relationships we do not wish to stay in. Start making plans for the life you want to have after that person is no longer a part of your life. This will make you stronger. Feel the fear, but do it anyway--carefully and with the help of others. If you give up, nothing will change.
