I'd like to elaborate on this "walking away" idea. If you get to a point where you are in total control of your emotions, I think you can represent yourself in a different way.
Ponder this. A girl is very interested and begins to play games for whatever reason. Perhaps she has her own issues, perhaps she just looks at men as disposable and fun to play with. You catch wind of her playing games. Now if you follow the threads of this post you "walk away" into the sunset, believing yourself to be amazingly strong and maintaining your power. You laugh at the prospect of being played with because you walk away at the first sign.
Now, let's take it a step further. Say you don't walk away at all, ever from anything. Say you face it like a man, however you control your emotions. You eliminate all feelings for her whatsoever. You don't walk away, because you don't have to. You simply remove your emotions towards her and push her to the outskirts of your life. You don't take calls, don't hang out, don't initiate, don't compliment in fact you stop thinking about her. But you never walk away. You never insult her. You never even hint at the fact that you are even the slightest bit effected. You don't have to walk away and remove her from your life, you just aren't interested anymore.
You take the emotions you were feeling, openness, caring, loving and you eliminate them completely from your interactions. You don't walk away, but your emotions do. Then it doesn't matter that she is playing games with you because you aren't interested anymore.
Now here is the point. This is the pinnacle of character and strength. Walking away is a sign of weakness. You walk away because you can't handle staying in contact with her and can't handle the way it makes you feel. If you were really strong you could just withdrawal your emotions from her entirely, move on from any romantic prospects and you soon become untouchable.
Never walk away from anyone or anything. Build a life where if someone enters it, they are a part of it indefinitely. But if she displays her bad character then you withdrawal your emotions. You can even answer calls and texts if you want but the key here is to become a master over yourself.
Keep her on the outskirts like an orbiter. Walking away makes you a chump in my eyes. To me, we walk away because we can't handle feeling emotion. If you can figure out a way to feel your emotion and control it, operating from your masculine strength then you truly are untouchable. You don't have to walk away from anything or anyone you just don't feel anything towards her. She becomes meaningless in the scheme of your life so whether she is contacting you or not and whether you are open or not is irrelevant because you aren't interested.
The reason to do this is that more people that know your character the better. She WILL become powerless. She will see that her games don't even effect you. Nothing she can do could ever effect you because you are in control of all of your emotions. She wanted to play you? Big mistake because now you flipped the script and add her to your list of do not emotionally invest.
Don't ever walk away from anyone. Keep them believing in your character and they will become your followers. In the end of the day its not what you know but who and if someone respects your character so much they will do anything for you.
