Hi All.
Great to be here.
Not an expert on any of the subjects discussed here but I think the best thing I can do to avoid you asking tons of questions about my question is to give as much info as I can first.

This is about a 20 year old male.
Parents divorced.
Lives with both parents they split a schedule. 50/50.

I have read about Aspergers for two over years to help me understand what is going on with the 20 year old and (not an official diagnosis, my observations), on every web page, every forum, reading what the leading doctors in the field say about Aspergers,,,,this 20 year old has it.

I have read about Narcissism/Little prince syndrome for over two years to help me understand what is going on with the 20 year old and (not an official diagnosis, my observations), on every web page, every forum, reading what the leading doctors in the field say about Narcissism/Little prince syndrome,,,,this 20 year old has it.

Keeping the above facts in mind, I have never found anything on the net about the following behaviour.

This 20 year old male who is 5 ft 10 200 pounds still has physical contact with his mother that IMO would appear normal if this young man was 5.
He regularly climbs on top of his mother, put his face in her neck and in a baby like voice says I love you mommy. If she is in bed he climbs on top of her (in a way that one expects lovers would do) put his leg over her, puts his face in her neck and makes whimpering baby like noises. If she is working i the kitchen he comes up behind her put his hands around her waist and sways back and forth, the way one would expect watching lovers dance. He constantly rubs his face in her neck. There are times when if her housecoat is slightly open he touchers her thighs in a way one would expect lovers to do.

I think I have said enough about his behaviours. I will add that there have been times when friends or neighbours or family members are visiting, witness these behaviours and literally look shocked, freaked out, puzzled. One girl who this young man is friends with (platonic) came over once for dinner and to spend some after dinner time hanging out. About 30 minutes into her visit he climbed on top of his mom on a chair, snuggled her like infants do, in a baby like voice said, mommy what time is dinner,,,,,,,, his platonic friend's jaw dropped, she looked at her phone, said oops, something came up and I have to go, and darted out of the house, and yes,,,,never returned since.

FYI This 20 year old man shows zero interest in dating whatsoever and has very few if any, real friends.

SO!!! Regardless of the fact that his mother either believes this behaviour to be normal, or finds it abnormal and just goes along with it, she says nothing about it.

I am the new man (as it were) in her life. As I said. I don't jump to conclusions about things and blurt out thoughts or comments. I read. Study. Try to find out what the pros say about behaviours.

AGAIN. I have read tons about autism/aspergers, child behaviour, and little prince syndrome and have NEVER found anything on the net about this (what appears to be,,,IMO) very odd behaviour for a full grown 20 year old man.

Any thoughts will be much appreciated (or websites that discuss such things.

Thank You
