I think this explains it all.. at least from our perspective..
Most Helpful Girl
that's a sweet song, but you can't do someone wrong and only decide to change when they reach their breaking point. maybe that will teach him to appreciate the next woman who comes into his life. everythings not meant to last forever1
Most Helpful Guy
More often than not, what usually happens is that the guy gets too "comfortable" in his relationship and stops paying attention to his girl. This leads to the girl noticing and blaming it on "little things" since she clearly knows that she's feeling miserable but she doesn't know why. When she finally comes out with it, it throws the guy into panic mode. Since the guy in this case is acting out of desperation and attachment rather than genuine, whole-hearted love for the girl, this only worsens how she feels about him and drives her further away.1
