I am so confused...my marraige is breaking....please help?

got married to my wife in june of last year in india ( arranged marraige). We fell in love and i joined her in us two months later. But as we started living together our fights started and she lied as if she was going dowsatirs and left for her brothers house so stays close by. This got me suprised, and we again patched up and she came back after i appologizing many times. This occurence went on 5 ot 6 times. Our fights were probably every month on issues like money and family respect. I told her we should spent jointly to spend a quality life and give both of us a sense of security and trust. But she brought her brother again in the middle and i was told to take care of the finanaces or she will leve and i did that. But i wouls tell from time and again her family does not like me and her brother is breaking our marraige by slow poisoning our minds everytime she will run to him. I know it is not him she is the one who tells him about our fighst and he is being a brother. Now ourbaby girl is born and she is 5 days old and cause of verbal fight again her brother this time called the cops and we have been sisnce separated. I wne to their house 3 ot 4 timmes apologised again, she tells me when her brother is not there she will be back and then her brother calls me and tell me he will not sent her back unless i take counselling. I feel being compelled in this relationship and now feel like divorce is the only option (her brother has mentioned the same) and going to my india forever. the brother is acting very adamant and is not ready to sit us down and speak. he ssys he lost his trust in me and does not want to beleive my words. I realyy love my wife and do not want to lose her, but i felling very confused and very emotional. I do not kanoe what to do??
