This is pretty much where I've been for a while now, except my gut does not say WH sexually abused AJ. That doesn't mean he didn't think it, and it doesn't mean my gut is right about anything. But to me it's always been about money and possessions. AJ was one of those possessions.
WARNING: What I'm about to say may seem harsh, but it's my own opinion and observations, and in no way is intended to be judgmental of AJ's mom. I do not believe that she ever did anything intentionally to put her daughter in jeopardy. So here goes
To me it seems like JH used AJ like some sort of emotional collateral in her relationships. When she wanted to be with a certain man, she wanted that man to love AJ and make her the center of his world. When she no longer wanted to be with that man, or that man didn't want to be with her, JH wanted him completely cut off from AJ. That was the "scorned man's" ultimate punishment in the end, and the "next man" was presented the awesome opportunity to love AJ and be her dad (NOTHING sexual). We are told this happened with bio dad, with Zach, and I think it happened with Wes. Sadly, I think this was emotional immaturity in the extreme on JH's part, and I think it was a ploy that had worked for her in the past. Zach has been very open about how he committed 100% emotionally to AJ and JH, and when JH decided it was over and convinced AJ to shut him out, too, it shattered Zach. I think that in the beginning of his relationship with JH, AJ was their glue, too. I also see indications in both relationships with bio dad and Zach that money and "what the man could provide" were make-or-break relationship criteria for JH, and if you didn't provide as JH expected, you were cut off from her and AJ. Similarly, when Wes began jeopardizing the family's financial and emotional stability and safety, JH realized she had to take action and get WH out of the home (and rightly so). Only this time she wasn't cutting AJ off from men like bio dad and Zach
she was taking AJ (and AJ's baby sister) away from a psychopath. To me it's important to remember that while WH was apparently good to Zach's daughters, they were still emotionally and legally Zach's daughters. But JH, AJ, and the baby were emotionally and legally WH's. If AJ rejected WH along with JH, then 2 out of 3 of HIS girls (JH, AJ) were against him. I don't think he had the maturity or the self-control to handle that "like a man" (to use his ridiculous words). If WH hurt AJ, I think it was because she stood up to him and made it known that she would not be "his" any longer.
At this point, I really wish this would turn out to be a crime committed by an unknown or unrelated perpetrator because the repercussions for the family and close friends will be so much worse if WH is proven guilty. A "guilty" verdict for WH in this crime will be nothing compared to the life-long self-imposed guilt her loved ones will feel for having accepted and trusted WH. Guys like WH never feel guilty about anything, just victimized. It is the actual victims who will feel weighed down by misplaced guilt if WH did this. And that breaks my heart.
