AS partner cheating

Hi, I'm new to this but my partner is recently self-diagnosed AS. He is very intelligent and high-functioning. I just found out that he's being cheating on me in a non-sexual relationship for 3 years with a much, much younger woman  (And, please, before anyone asks, yes, you can cheat without sex or even romance.) Having given this a LOT of thought I think this is more to do with narcissistic personality traits than AS. He's done online tests for various personality disorders and this one fits best to his characteristics, although I appreciate it's all very fluid. Any (helpful) comments or advice gratefully received.

  • hmm rather odd, i mean most people with ASD struggle to find any friends or relationship anyway and remain forever alone.... rather rare for one to not only have a relation but also be cheating on that relation and having another. could be that his self diagnosis is wrong or not thought out well enough. what makes him think he has ASD if hes such a stud? lol

  • He does find finding friends difficult. The ones he has are very long term and from his youth. That's one of his excuses for conducting the relationship behind my back, he didn't want to lose his "best" friend and he knew that the world, not just me especially, would see this relationship as being "abnormal". Even my therapist (who I just started seeing because of this situation) said that the relationship was not something she had ever seen before (because of the lack of a sexual element).

    Most therapists have no clue how 'autistic' people function - they are winging it - and taking your money.

  • Granted. But how many 26yo do you know who see a 60yo on a regular basis and who email, whatsapp video call every couple of days? Their communication is juvenile in  essence i.e. something I would expect of young teenagers. My therapists point was, why is this girl in such a relationship? It is not "normal" as in it pretty much never happens. I personally think she has "daddy" issues but this is getting off topic as I don't care about her.
