How do I get this type of girl? She is very different from other girls.?

So I met this girl and we have been talking for a few weeks now. She is a really good looking girl with good personality, but there is a drawback. Other guys tried to get her, but they gave up. She told me that I'm the only one that lasts longer than anybody else. That made me really happy and proud when I heard that. She had two boyfriends before, and they broke up. She told me how they broke up.She said one of them was a jealous type and yelled at her when she spent too much time with her friends than him. The other guy wanted to get attention from her. One of her friends liked him, so he pretended to flirt with her, so she got mad and broke up with him. She told me that when she likes someone, she doesn't like to show any feeling and affection. She does not like to call or text the guy first because she is a girl. She doesn't care, she admitted that she has a coldhearted and cannot change it. Now it's my turn i thought such thing would never happen to me right cause I thought i was better than those guys, WRONG. I now understand why those guys did that to her. She's interested in them, but doesn't show any interests. I'm now in the same shoes. She is doing the same thing to me. I know she is interested in me, but it's hard when I'm the only one that tries to please her. Many girls desire me and wanna be with me. Even her friends admitted that I'm good looking, I can have all the girls I want, but don't why my heart is always with this girl. I was thinking about disappearing for a few days to see if she tried to contact me. If she doesn't try to contact me, i will leave her for sure. Any thoughts on how to deal with the situation like this?
