I am really confused and need help 10 p0ints?

my ex girlfriend breaks up with me and says she want s to be friends. so me and her are cool and have no problem with each other. i see her at a gettogether we say hi then bye. her friend starts talking to me (just talking) my ex comes and pulls her away. when she gets back she says to me i cant talk to you no more. when i ask why she says my ex dosent want her to. her friend tells me that she really liked me but made a choice at the time and dosent know if she regrets it or not. i talk to my ex saying lets talk because i wanted to know where we stand. she says sure. i call she ignores i text she ignores. i see a negative comment on my myspace with here and her friend made directed towards me telling me to f off. so i delete the both of them. now her other friend is trying to add me(i think its my ex on her friends profile) i dont except. i see her at a party now i dont look at her or even talk to her i chill do my thing have fun leave to go to the club and i get a text saying "wow nice seeing you tonite". i dont reply the next day i see something she has written on myspace saying "the worst part is seeing you and not being able to be with you". im thinking she cant be talking to me because shes a ***** to me and plus shes got a new boyfriend. even though i deleted her some how i think she is still seeing my page.Because i ignored her for a couple days now her status says and if i never see you agin i dont care. ive been with lots of girls but never in a relationship i think this is the first girl i ever actually liked. but i dont want to put myself out there just to get rejected like i have been. and how can her feelings just switch from hating me to liking me to hating me. im not good with this relationship stuff this is new to me i need advice and help on what i should do. is she just doing this all so i i put myself out there so she can turn me down and have the upperhand or something? dont want to feel worse then i already do.
