I am not a big Willard Harley fan. But, he did claim to have surveyed betrayed spouses that had been raped. He says he also included betrayed spouses who had lost a child.
He claims that virtually every one said getting over the cheating was tougher.
Now, here is where a distinction needs to be made between trying to quantify pain, and compare it. I would bet that any BS, given the choice, would undergo the betrayal vs losing a child. I know my pain would be immensely greater if one of my children died.
BUT, Harley is not claiming the pain of betrayal is greater. He is claiming the recovery is tougher. Same as regards rape ( and, BTW, I was molested as an 11 year old, so I have some frame of reference).
He claims infidelity is a tougher recovery for a number of reasons, some already menin this thread.
First, there is the volitional component. You are intentionally betrayed vs no intention when a child dies. You have no doubts re your child's s love for you or that you played a role, usually. Not so with infidelity.
Second, as someone already pointed out, there is much more support for a grieving parent. There is a funeral, a wake, folks console you, bring casseroles etc. Rape is a bit different, but still, there is much more support.
With infidelity, folks are upset if you are not over it in a few weeks( I mean Erica on All My Children was, right?). Everyone seems to understand the severity of the trauma of rape or loss of a child. Not so infidelity.
Third, with the loss of a child not all your past memories are vitiated. You do not look at your photos of the family trip to Disneyland and wonder if your child was faking loving you and enjoying being with you. With cheating, you do.
Finally, while I am positive that there are triggers with rape or loss of a child, with infidelity the reminder is always there in the form of your spouse.
The guy that molested me was a stranger. I had no trust relationship with him. Maybe that is why I think it was easier for me to get past.
And, again, I would take being cheated on any day vs harm coming to one of my kids. But, this recovery vs depth of pain distinction is what Harley was talking about, I think.
