Need help =(

:(

so here is my story cut down to a short version

ex girlfriend dumped me went on the rebound,
things happened i got tired started to ignor her,
she then noticed she loves me and what not dumped her rebound and we were working on US
the first week was going so good, she was happy i was happy we had plans and everything.
turns out she had become deprressed sometime while with her rebound, ig uess because she never healed and missed me,
today i saw her, she came over to my house and we had fun everything was going good.
her rebound texted me saying "shes all yours bro"
i ignored it, i guess she got a text from him to, she later left
turns out the rebound went by my house to see if she was over,
she later texted me saying "dont text me or call me to this numer im giving the cell phone back, talk to you later"
(her rebound had bought her cellphone for her and was still paying it.

later came and she did call me but from the hospital.....
i dont know what happened with that guy but her depression crashed on her and she ended up at the hospital.
whats worse is her mom is blaming me for it,
at first i talked with her and she seemed fine and told me not to worry,
i then texted her asking if there was anything i could do for her or if i could go see her,
she told me to not call or look for her daughter again, if i love her to let her goo =(

this hurt so bad!
why are they blaming me for this?
shold i lose hope and not call her anymore?

what do you guys think??
am i really resposable for her being like this?

i sent her a email tell her im here for her and that i would like to know how she is doing,
i told her her mom asked me to stay away from her and that i was going to respect her choice,
but i told her that i am here when ever she needs me....
