You have this thing/issues with your couple and it's complicated. You guys are arguing and complaining about the "boringness" of each other all the time. But you still hang on to the relationship even at some point you realize that it might not be working out anymore, no matter how hard you try to save it.
What I don't get is why do you still hanging on it? What benefit that you may get? Hurt and frustration are definitely not the greatest feeling. Just let it go and end it. Is it so difficult?
