My wife's near 16 year old son frequently wants to take maps with his mother. She cuddles, snuggles and "spoons" with him. Last night, while sitting on the couch, his leg in her lap, he says, "mom, rub my legs. don't massage them, just rub them".... Followed by, "just rub the hairs"... The seems highly abnormal for his age. She claims their closeness is based on, that for so many years, she is all he's had. I am confident nothing sexual has or will take place, I am just sort of disturbed by this behavior and am not sure of the nature of his attraction to her.... Can you give me some guidance as to where to direct her to educate herself,as she seemingly doesn't want to hear it from me, discounting my concerns as "jealousy" and/or "not understanding" their relationship.
