Father Wants Custody of 4 Year Old Daughter

My question involves a child custody case from the State of: Texas

Ok guys, hope i'm posting this in the right forum and i'll try to be as brief as possible. I have been married to my wife for 5 yrs, we have a 4yr old little girl and I have an 11 yr old stepson from her previous marriage. This has been an ongoing situation but recently has come to light with how bad it was. Wife has been abusing prescription medication for over 2 yrs, recently found out just how bad it was, 72 dr visits last year alone, up to 25-30 vicodin a day, but somehow still very functionable, told her she has to get help or it is over. She agreed to get help, went to rehab, doctor put her on suboxome to help her, she checked herself out of rehab after 8 days, saying she can do it on her own with just the suboxome and some counseling, fast forward 2 months, i thought she was doing great, taking the amount prescribed to her daily along with her anti-depressant until she started lying again about losing her pills, needing to go to the dr to get more, changing back and forth from the retail to generic to get the refills earlier and hopping from doc to doc..i am at a loss...i know what i need to do, but here is my dilema..the minute i tell her its over she will take my girl the first chance she gets and will be gone. Why do i think this? Because she did it with her stepson and bolted from Utah with him without telling the father, oh and the fact that she has a DUI bench warrant that i just recently found out about...i know, i picked a winner, but besides that, i need to make sure my little girl is a part of my life, every day i can..i have a stable job for 15yrs, (she doesnt work) never used drugs and never been arrested. Will the courts side with me? I have a lawyer lined up and he says we should be good to go, but i'm still very nervous, any feedback will help greatly, thank you!!!! oh and she is using her child support for her son that goes into her own account to fund her pill habit apparently while i end up paying for everything for him..and if i could get him, i would in a heartbeat as well

The courts will "side" with the best interest of the child.

You are married. Currently, your wife doesn't work because you are supporting her. You are "paying for everything" out of money that is both of yours right now.

Addiction to prescription meds is serious. It may take years to truly get over it. I imagine if you leave, it will probably get worse for her. Or who knows, if you are threatening to get custody she may straighten up and decide to get serious about sobering up.

It's impossible to tell what would happen at this point, because the two of you splitting up could lead to unlimited possibilities for the two of you. She could leave with the child. You could leave with the child. She could get sober, she could get worse. She may be awarded your place of residence, or you might. There are way too many unknown factors.

I hate to go straight to a "cop-out" answer, but you should really consult with a family law attorney.
