Is this girl play games with me?( i need ur advise please help)?

She's wasting your time. By the sounds of things, you're a really sweet guy with lots to give in a relationship. If she is going to treat you in the ways you described, don't bother with her any more, because she clearly doesn't deserve someone like you. Go find a girl who takes an interest in you, isn't selfish, has respect for you and knows when to say thank you for helping her. Good luck.
