This is the problem, once people has the person they want. they take it for granted. This is when you lose that person as someone else may just make them feel the way you did in the beginning. Keep doing what you did in the beginning.
I started learning this a few days ago! If i don't want to fight even though it will be good for the other person it won't for me so i can step aside and that person will have to learn how to solve things with out fighting :) tough love my friend
