Did one of Kaine Horman's love interests get rid of Kyron out of jealousy?

I've stated for months that Kaine Horman has been involved in BDSM and that it could have been one of his male or female sex partners that got rid of Kyron Horman either with or without Kaine's knowledge.  Most likely they helped Kaine Horman kidnap Kyron (or kill him) because Kaine was afraid what the doctor would discover¹ and/or was afraid Desiree Horman-Young was going to regain custody^2,3.  what I find odd is the statement Kaine Horman recently made about "his dating card being revoked"  Apparently he is admitting cheating on Terri Horman or is admitting he was engaged in "inappropriate behavior" after Kyron went missing (Kaine's sockpuppets call Terri Horman's alleged "sexting" inappropriate so they should feel Kaine dating within a few months after Kyron's disappearance is just as "inappropriate")

But he does second-guess people who come into his life now, saying that his dating card has been revoked.*

1. My alternate theory about the Kyron Horman case

Seeing that Kaine is a malignant narcissist and control freak with OCD ( http://blogs.wweek.com/news/2010/07/01/kyron-hormans-family-boots-ww-and-the-oregonian/ ) it is so easy for me to see he would plan on setting up Terri - and kidnapping Kyron so he gets full custody (not shared with Desiree) and as payback for what Desiree did to him  --- and the way he would get Kiara without having to share custody with Terri.  As a a malignant narcissist he does not feel remorse for what he did - and can pass any polygraph test.

Terri was about to take Kyron to see a doctor because she thought Kaine was molesting him and Kaine found out about it so he had to hide his guilt so he acted before the doctor's appointment took place instead of waiting for summer vacation.

2. Desiree Horman-Young : manipulated and deceived Sock Pupet or perpetrator ?

In her interview on Today, Young also said that she tried to get custody of Kyron a year before he disappeared, but Kaine would not allow it.

3. Parental Kidnapping - not as uncommon as you think 

What hasn’t been made public is the fact that, a month after filing for divorce, Young sought a restraining order against Kaine Horman, Kyron’s dad.

At the time, she had a 7-year-old son from a previous marriage. In court documents, Young said she feared Kaine Horman would “remove our children from their residence.” It’s unclear whether the couple was living together at the time. Washington County Circuit Judge Donald Letourneau granted Young’s request, forbidding either her or Kaine Horman from taking the children without the other’s consent.
