Before my husband and I married we had a child. Four months after he was born he left. A year later he came back into our lives. He convinced me to grant him joint custody with no child support order in the state of Texas. My son spends one week with me and one week with him. Well,we married and now are seperating. He is verbally abusive to me. I am having a difficult time sharing our child with him. He has also threaten to take him and I not know where he is. What are my chances of retaining full custody?
