Dammit I think I messed up... Help.?

well i personally believe that she is def. testing you....she is trying to see how long u can deal with this(meanin her sayin i hate you but i want you back). I do think that maybe she still does has feelings for you but at the end of the day...would u really want to put yourself thru this whole "i love you but hate you" situation. of course maybe u should have called her or a simple txt explain why you couldnt come to the party in the beginning before her calling you first, BUT no time to go back on "shoulda-coulda-woulda's" its the past and it already happened. But if you truly do love her and want to work things out then yes continue to try, then again if at anytime you feel like she is testing you over board or playin WAY to many games, then maybe she just isnt the right grl for u. period but seriously ask youself is this worth it?
