Divorce Advice for Men | Fathers Rights Divorce | Child Custody

My wife is disabled and refuses to go to work. She is taking some college courses just to have something to do. Her parents pay ALL her household bills, have given her a house and a car; her parents pay her car insurance as well. Her parents also own a grocery store and provide her with all food and necessities to clean the house. If there is a problem in the home her parents pay for all repairs. We have been seperated for 6 months and she rarely lets me speak to our daughter even though I call every single night. She has called my work and told lies about my having an affair and not sending her any money. I have the written signed statements from the people she spoke to about this and she called back the same day admitting that what she said earlier was a lie. She has been harrassing my friends and co-workers with phone calls. Her phone bill, if subpeonaed will verify this. She went to the casino in January and won almost $500. When she told me about it she immediately asked me to send her $100 because she didn't have any money. I have proof from Wells Fargo Bank and Discover card that she took out a credit card in her name but gave them my checking account number to have the payments made by me. She was never and has never been granted access to this checking account. I have the written proof from Discover that she did this. All told $322.23 was deducted from my checking account between December 1 and January 15. I have bank statements to attest to this. Luckily, my bank refunded all the money back to my account. Based on this info what are the chances of my getting primary or sole custody of my daughter?
