She is a drug addict. Drug addicts, alcoholics and other people with addiction issues are never "model parents." With addicts, what comes first is the drug of choice. That doesn't mean an addict doesn't love his or her children or want to have custody or try to care for them. It means that their priorities are focused on their addiction.
The judge did the right thing ti grant Crystal a rehearing. If there was any chance that she missed the hearing because of a paperwork problem of some sort, she deserved a shot at getting her kids back. The attorney, of course, was filing a document that served her own needs. But she is an officer of the court and is obliged to tell the truth in such a sworn statement. If she says Crystal is an addict and Crystal's father says she's an addict, that is convincing to me.
I still don't see the point of minimizing Crystal's problems. I don't know her personally, so I of course have to go by what is in the media. By all accounts, she has a drug problem. Many parents do have problems with drugs and alcohol and their children suffer accordingly. It doesn't help Crystal to minimize or deny that her addiction impacts her ability to care for her kids. Addiction also doesn't mean, necessarily, that a parent should lose custody. Many addicts get help and get clean. But if kids are at risk in a house with a father and stepmother involved with selling and taking drugs, they are at risk when their mother does drugs too--because she has to "deal" with dealers to get them. Again, my hope is that she, unlike Ron, will get help, get clean, and make a good home for her children.
