My question involves a child custody case from the State of: Texas
My ex-husband and I were both granted joint custody of our no 4-year old daughter. In 2007 while I was deployed, he took her from my mom, dumped her off to a couple only he knew while growing up, and went back to Texas. He stayed in Texas until October 07, and hadnt had any interaction with our child. He then moved in with this couple (Nov 07) and our daughter, started working and had almost no interaction with her. Two weeks later he moved out and saw her once until February 08. The entire time I had been deployed he had cheated on me, and was at the time being sued (and had warrants) by two parties.
When I returned from deployment (Jan 08) and got my daughter, he called twice to say he'd be coming to see her, but has not. And he has not called again since Oct 08.
I have reason to believe (no phyisical eveidence) that he got a high-school girl pregnant. He has been arrested before for drugs and was on probation (2005).
What can I do to get sole or full custody of my daughter?
What is the difference (if any) between sole and full custody?
