Your point is well taken. But there is also an element of pressure and defensiveness to that dishonesty, is there not? They get in trouble, so they deflect by lying rather than fess up and accept consequences. I have to imagine that there is an element of that in play in the context of treatment, particularly involuntary treatment.
In this case, it doesn't look like she's acting in her defense. She's the one who called the police and she's the one who wants charges pressed. There isn't really any defensiveness involved.
That isn't to say she can't be lying. She could be trying to shake him down and if he has told her she's cut off, she might see this as her only way to cash out.
But to me it's even money on who's lying. Both of their life narratives so far indicate that they are capable of doing what they are accused of doing.
Deflection to addicts knows no boundaries. The element of "being caught" or "being in trouble" is not necessary in the equation. What
is an extremely overlooked issue, is addicts' need for acceptance and attention. They are human, after-all. What commonly happens, is this need for belonging is so strong, yet so distorted by chemicals, that their actions to get the attention they want ends up hurting the person they want it from.
Simply put, many addicts can't differentiate between love and hurt. As simple and as silly as that sounds, their cognitive skills are so decayed and so warped that "the big picture" doesn't exist. Short term, "in the now, to supply my need" is as far ahead as they can comprehend.
Again, this isn't the case for every addict I've dealt with, but you'd be astonished how predictable severe addicts can be. You can almost write out a script for the next of week their life after only a few meetings with them
I've somewhat lost where I'm going with this... But the point is, I'd really wait to hear all the details before I made any judgement on this. I'm sure both have much fault in the case, but the victim card being pulled by the mom is a whole lotta BS, imo.
