I don't think there was physical abuse either.
I doubt there was either and emotional abuse can be very subtle. It can take years for even the person in the marriage to recognize mental abuse.
I don't know if this occurred in their marriage but I do think Chris tried to appear to be a loving husband and father.
We know it's likely he didn't feel emotions like most people do based on the things that he googled about how one feels when they're in love.
I think for a long time CW invested everything he had in his marriage and was disappointed when he didn't feel adored by his wife and kids any longer.
He probably equated physical feelings and sex with love and this is why he was so obsessed with his lover and couldn't bring himself to be affectionate with his wife anymore.
It wasn't until this time that Shannan felt something was very wrong in her marriage.
It's so sad and unfortunate that she tried so hard to repair their relationship in the days before her murder.
If only Chris had been honest and faced reality instead of pretending everything was going to be ok.
He made a conscious decision to get rid of his entire family instead of giving Shannan and his children a chance to go on living their lives without him.
He thought only of himself, with no regard or empathy for his wife and daughters. It was easy to kill them because he had already distanced himself from them and objectified them.
These are the things he needs to admit if he has anything to say at this point at all. He needs to take full responsibility for the murder.
Instead, he has decided to be the focus of attention again by making up new and shocking details about the murder.
Does he really think this is what Shannan's family and loved ones want to hear?
He is just catering to all the people who read gossip magazines or are still obsessed with the case or believe Shannan somehow brought this all on herself.
