DUMB!

Ok so i had this friend, i thought we were best friends she was the only one i had after i gave up my other backstabing friends and well now im not sure i want her as my friend. She keeps saying she is pregnant but is always having a miss carage, but none of the dates match up. The most resent was today, she said a week ago that she was 3 months along but not even three months ago she said she had a miss carage with this guys baby who wasnt her boyfriend but now she is three months pregnant with her boyfriends baby? When today she said she was a month along and was having a girl when she had her miss carage yesterday, first of all you had a miss carage a month not even a month before school started you were texting me at the time and wouldnt go to the hospital, second you say first that your three months along and its your boyfriends baby when you and your boyfriend didnt even have sex tell two weeks after your "miss carage", third no one can tell the sex of a baby one month in. I have found out that this girl is a lier and the fact that i am supposed to be her best friend sbut she tells the girl who is living with me that she is "pregnant" before she tells me and also tells a guy that she just met, does that sound like a best friend plus she hasnt even talk to me in two weeks and i have to hear about the miss carage from the girl who is living with me. I really dont understand if she is trying to push me away by being best friends with the one person who has hurt me A LOT and also trying to hook up with my ex-boyfriend who all girls know friends dont date there friends exs no matter if they have feelings for them or not. Im trying to be here and be understanding but how can you be here for someone who chooses people they "hate" over there best friend?

Maybe i never was her friend at all, maybe i was like one of those guys to her that she could date mess with and then just throw away? Well im not a guy and im not someone that she can walk all over! She will learn that walking all over poeple will get you no where, expashaly people like me.
