I am wondering, then, is the MLCer reenacting the abuse they experienced onto us, the spouse, to make us the victim?
My ex grew up with an abusive stepfather, who had a very strong regional accent. In the worst moments of cruelty to me, he uses this accent. It's really nasty. Once he even told me that I reminded him more of his abusive stepfather than anyone he ever met.
The OW he hooked up with highly resembles his mom, in personality, socioeconomic background, and looks. Now they are still together as a result of an unplanned pregnancy — when my ex was the same age as our son is now.
This is a shocking detailed reenactment, but I can't tell if the mind has a "method to the madness" or if this is just totally unconscious mess created by a fearful and unstable/damaged mind. After all, it seems at one point these men and women could control it. Something had to happen to tip them into this state.
