Guys, if you have a friend, and you promised something to them, and somehow you haven't had time to do it because of your time (in my case is exams) and that person started giving you cold shoulder and actually stop replying all things you sent to that person. Should i care (like i still do) or should i just stay away from her? because i really feel like i'm being used and in the end i get nothing out of it....just me putting on trust to her, but she don't put me in her heart anymore....moreover, i'm sick and tired of giving a damn on everybody who doesnt even give a about me.....

So, between leaving her because she never actually know how to appreciate you as a friend?

Or, 

Stay and try to talk to her even though she wont reply anything and you will feel like a hoping for something that never come?

The truth is, i still care for her, but then, i get sick and tired of these jokes she's playing me....hm....

But i rather choose the second choice...

What do you think?

Any advice?
