What if he does find someone else & treats her properly
I doubt it will happen but if it does, good for her. You would not want someone else to hurt the way you are hurting right???
Now question for you:
What if down the line you find someone else who treats you properly?
Wouldn't it be awesome? but you know very well it can't happen as long as you are emotionally entangled with that person who treats you like crap.
