full custody

[tinnitus]

my wife and i are now seperated, it has been just over a month and we have a 4 month old baby boy, she had me beaten up by her father and his friend in our home and also she has started false accusations, accusing me of hurting her on that night which is untrue, she has said that i have had no interest in our son and have never changed a nappy which is also so untrue, in our short relationship she has been abusive to me and also my family who have never done anything wrong at all, she has tried to cut off my friends and family so i had no one left. when i married her it was as though i married her mother and father and not her. she even said to me at one stage "do you not think it would be a good idea to adopt liam (our baby) to my mam and dad?" to which i replied "dont talk so stupid" . many times she would call me at work crying down the phone and saying that she couldnt cope and i could here the baby crying in the background. i changed my job to be closer to her and our baby but now things just seem or feel like they are going against me. can you help.
