Hello Herculepoirot: Hm-m-m-m... I don't know about this. Personally I was not abused by my mother. I was an only child. And, if anything, she clung to me almost to the point of suffocation. (It was all many, many years ago now.) Eventually I moved away to go to school & never went back... except for a couple of brief visits.

It would be interesting to know to what extent sons do experience maternal abuse. I suppose part of the problem is that men, in general, are not supposed to have feelings; & admitting to having been abused by one's mother might just cut a little too close to the bone...
