False allegations of abuse?Family issues?Marriage?Son?

It's been about a month since I've seen my son and everyday I wonder why. My worst nightmare happened about a month ago when my wife filed for abuse and protective custody of my son. It all happened over a simple argument we had one sunday afternoon about trust and communication...not the everyday topic most couples tend to have but we did...the argument led to a lot of screaming and me moving back with my parents...worst mistake of my life. Me and my wife always argue and my safe haven is always my parents....why you asked? We lived at her families home( 3 story home, just family)...they never liked me...and quite frankly because I wasn't white or rich...neither was her...hell...she never finished school and had a son from a past relationship and I accepted all of that...I was in love...I loved her and my family...Again, the argument led to me leaving the home...no big deal right? I always left the home for 2-3 days and came back when we had a big argument...it was normal and common...I wish I never left that day though..3 days later I came back with the surprise of my life....a restraining order....In my mind I was shocked and confused..."What the hell?"Why?" We always argued and said things but never meant it...It seems like her family got wind of our argument and decided to push for me to leave...now at the same time she was furious as well....we argued and said things...I said I was gonna take my son away...She said no...well the end result was her having full custody and me going for part time supervised visitation...Again, very painful and really surprising...I know my wife was upset but this is something she would never do...Even worse she wrote that I abused her..."I was like no way!" That was never me...I never abused my wife...We had arguments...got face to face...we thrown things at each other but she said abuse...never that...I was quite hurt and saddened...Not only did I get placed in that category but they court gave her full custody until our court date....I was surprised and wondered why? The court never heard my input...there was no abuse...just arguments..why does she get custody for lying? I still do love my wife...but in my heart I believe her family made her do this...why not? What's the best way to get ride of someone without killing them? Court...false claims...that's what it was...Today I stand a month or so away from my court hearing wondering what can I do? I love my son and my wife( even though she did this)...were still married... but why this? why is it that the courts favors women more?...I'm a 21 year old here suffering because of her families lies...I don't see my son..and I'm labeled an abuser just because she wrote it on paper. Indeed I will get myself a lawyer and fight this to the end...I would like a social worker to see my daily life..run a test..lie dictators...whatever they want I'll do...I don't want to be branded an abuser just because it's the best way of her getting my son and her family getting rid of me...In the end the one thing I always believed would break our relationship did...her family...her noisy, lying, racist family...What can I do? I'm willing to do anything to be with my wife and son..or just my son...We are technically married but doesn't she have the obligation to work this out with me? Why would she want this? I don't want this for my son and I don't want that label placed on me...I'm not an abuser...I loved my son...I even still love my wife...I hate that family...so much...why would they go so low...what can I do?? I can't compile evidence...shes has all the power in the world...shes a women..she put in the paper work..lied...and screwed me...We lived a happy life for the 1 year we were together..nothing serious...violent..we did put each other down and said things but nothing to the extent of abuse..nothing enough to break our marriage...a lil argument has led me to this...has led me to 1 month without seeing my son..Even worst the panel against me..including the judge were all females. And made facial features as to say I did this. Isn't that illegal? I walked that day to court without an attorney thinking this would be worked out and but no...Do I really stand a chance? Sometimes its not worth living this pain because it seems hopeless...how can I fight these claims...clear my name...and see my son.
