From GIRLS POINT OF VIEW , i dont know if iam being dumped or the relationship is just over?

i have stopped calling my girlfriend since amonth due to misunderstanding between us and now its consider split up from my point of view, however there are many things been going in behind, first i would like to explain that i had some warnings from her friends that she is just sort of playing girl who would like to go out and chill with no intention for commitment whatsoever. well , we been together for almost 3 month in ups and down relationship , however there was really good moments between us and i dont know whther she liked me really or she was pretending . until that date where we argued over breaking her promise to go and watch amovie . i talked to her the next day questioning her disappearance and she replied with anger like she complains why iam being rude to her. then i decided to stop calling her for 3 days until i made the last call . she acted SO COLD and DISTANCE like she answering my questions in brief , it was like 20 minutes until she interrupted me by saying ( hey bye...iam tired and i want to sleep) . i said good night and said i will call her tommorrow ..however i stayed a wake for the whole night analysing whether she meant to give me signs of BREAKING UP or wanted to drive me in away to break up with her or she was just ANGRY AND WANTED ATTENTION . i just stopped calling fearing that she might surprise me in the next call, put in mind these warnings form her friend that she is not type of girls who love . my second concern was when i asked her friend about her few days later , and she talked to her then replied back to me that my girlfriend complains about me not calling her , and i dont know whether she was angry because of that or she was giving this answer to depict herself as being innocent but deeplu inside she ended this relationship . I asked her friend to not discuss the relationship with her as i decided to GIVE UP ,however few days later i met her friend again and started to ask about her and i asked her in away like i wanted to get back with her , she told me if i wanted her to go and discuss the relationship again and i replied to not mention it as iam determined to give up . I feared if she went to ask her again she might reject me and i would be really heart . HOWEVER NOW i started to analyse again what if her friend didnt mention that i gave up the relationship and just told her he want to get back with you . In this case if she rejected that , its like i consider my self being dumped , specially that her friend was telling me she is not good for you and she is playing girl. so if her friend didnt tell her what i said , would that means i gave her the chance tor revenge . should in this case just go and call her , or iam still keeping my dignity . In overall and after all these details i really really LOVE HER SO MUCH , we had really good moments together and i still couldnt believe she was pretending , as we been going out almost every 2 days and we huging , cuddling and touching , she even said ( i love you) ...so please help me girls and guys to find answers for these analyses in my mind .....and how could i get back with her despite that all my friend and even her friends told me not to call her at all .
