It's extremely troubling that a person would have a child with someone they also suspect might be a pedophile.
It's from their own trauma which is valid but they clearly need help that should've come before conceiving.
Unfortunately, my son's father is similar in that he says random things (like my son being interested in my breasts, or me holding him up to place his back diaper on and then "slamming" him on the bed to finish/tape it cause he rolls and is v strong) are weird and pedophilic. It's horrible projection and strange.
