why god isn't answering my prayers

Hi i'm writing this with so much pain , i was in a relationship for past 3yrs , she ment everything to me she came from no where to change my life , i used to thank god for giving her in my life , she is from a family with financial problems , she cant even afford to buy good dress she was a student , i'm a student too , i used to save my money which was given to me by my parents for my food expenditure , and get her dress and all other stuff , i did help her study , and 6 months back she got a job , i was the one who helped with resume to even searching job , i was taking care of her like guardian , the companies managing director is not a guy with good motives he is trying to sexually exploit her , he has spent a great deal of money for her and got her extravagant gifts , she never realized that  this man had bad intentions , i did tell her more than one occasion , she felt i'm suspecting her and she broke up with me feb 17 , last month , i tried talking to her we live 100miles apart , i tried thro telephone she never returned my calls , so i did pray to god to give her back but never got any answer so , i decided to visit her in her office , that boss of hers hit me and they got me imprisoned and he persuaded her to file a complaint against me  , currently i'm in bail , my parents aren't talking to me much any more , she is blindly trusting that man with out realizing what she is doing , that man is trying to ruin her life , he did ruin my life for past one month i have been crying every min , have so much pain in my heart , i still love her ,why god is helping that man even though he is  ruining her life , why god never judged that man , i pray god for my gal friend's forgiveness why isn't god not listening to my cry , why he isn't wipe my tears , and the man who ruined my life is happy , all i got is pain , lose of my loved ones and tears , so when will i get justice , why wont god gimme back my gal friend all i want is god to protect her and answer my tears , i want to see a proof that god does justice , i feel totally dejected , i'm left with  nothing , me depending on my parents for money is not my mistake , this is what i got for being honest and truthful in love , what should i do , will god listen to me
