Never mind the “he said - she said” aspect of this.
What sort of jerk seeks annulment of a 24 year marriage with 5 children produced.
“Hey kids, this is your father. I’ve petitioned to have you all declared illegitimate! One more thing to remember this Thanksgiving! Merry Christmas, too, while we are talking about presents. Love, Dad.”
The sort of jerk that wants to avoid splitting the assets they acquired during the marriage.
