Can my wife keep me from my children without proof of abuse?

At this time my wife has a TRO on me(yet I have never been served , had to go to the courts a pay for the paperwork but still not served)My wife is saying I am abusive to her and my children. I have been deployed for about 68 months out of the last 75 months so im never home. Now her mother(which we have been living with and hate me because I am hispanic) said she will spend every dime she has to make sure I never see my daughters again and there is something in the court papers about i should be denied access to the children in accordance with section 153.004(d)(2) of the texas family code...it's something about ual ault.... yes we have two daughters born in 2004 and 2005 and this is just now being brought up? I asked the local police if any charges have been brought up on me, they say "no"I asked about domestic violence reports on me at the house, still got the "no" answer....so its a he said she said and the mother in law said and she has all the money and I am almost broke.... The court papers filed be my wife's attorney (paid by the Mother in law) is trying to appoint my wife as sole managing conservator of the children. Respondent(me) should pay child support, health insurance premiums, 50% of uninsured expenses, day care for children while case is pending. I should be denied access to the children and that i should pay all of my wife's attorney fees and interest. All this with no proof, we have been together since Oct 1995 and married since mar 2002. Her mom says we are not married because it was never recorded in the Arizona Pima county court system (wife didn't send it in, didn't want her mom to find out) even though its the person the performed the marriage responsibility to send it to the clerks office. My wife also does all the taxes and always files Married - filling jointly and the military sees us as married and I have copies of the license / certificate and she uses her married last name when it benefits her. I think she is more afraid of her mom throwing her out on the streets with our daughters then me
