Should i try to get my ex back if he is willing to change?

Many guys will say they will change when they start to feel lonely. I personally would not go back if i were you. You broke up with him for a reason. I've had friends that have gone back and regretted every moment because it was harder to break up the second time around. If you still feel for him, go for it, but remember, many people think they can change but after time they go back to who they really are. Make the wise choice, find someone who already has the qualities that you like and not someone that you have to change.
