Something I do know. I dated a lady with asperges and her son has autism. (I am quite sensitive so I am emotional but I have not been assessed yet so I can't really answer).
The lady I dated was very emotional. But what she did to deal with that is she would avoid situations which would bring out emotion... Put it this way. When our dating came to an end, I being too emotional wanted to make sure she was ok so I text her daily. She wanted to avoid emotional feelings so she asked me to stop texting her. (Ths next bit I over reacted as I do... I do tend to mess things up sometimes because I do not seem to have a central ground? I don't know). I then took it literally and deleted all the contact details I have for her and broke all contact entirely. Her husband (I introduced them shortly after we had finished dating and who was a good online friend but only recently has come back chatting on the site we were on) wasn't in touch except through a mutual friend, and now he is joining us back in the chatroom. I feel ever so guilty that I am at fault because I broke off our dating as I am a very "Off and on" character who, if I latch onto something or someone I will be full on, but if I don't I tend to not want to know or have any interest, but with people, I am too emotionally involved so like my ex girlfriend, I am... Well. Put it this way. I don't want to have sex before marriage because my emotions would get soo much deeper.. So if the dating ended I would be in such a mess... Suicide would be easy if I was in that state. So I hang back, and this is why I may find dating soo difficult. (But I only have had two proper girlfriends in my life so far).
Now am I on the autistic spectrum? I share traits, but I just do not know. Emotionwize I am quite sensitive. The odd thing is that when I am dating, or thinking of asking a lady out (Usually I try to get the lady to ask me out as I am not very good at asking out after not being able to judge other peoples intentions... "Is she just being friendly or does she like me?" sort of thing is where I have gone wrong big time, so while I do not get hints myself, I give hints, though it doesn't work as I am still single...), I tend to feel others are better then I am and I hook the ladies up with them and miss out on dating myself. I have done this a few times. Found lovely ladies and found them really nice gentlemen even though I was the one who was attracted to the lady myself and would have loved to go out on dates with her!
So to conclude. If I am on the autistic spectrum, I can say that those on the spectrum can be highly emotional beings and for many (If they are like me) far too emotional and will find ways to switch their emotions off in certain situations so they won't get hurt... If that makes any sense? It is this ability to switch off emotion by avoiding emotional situations (For example, I may go into a deep daydream of an entirely different subject to numb out my emotions to what is going on... Or I will think of nothing at all and go completely numb where I am closed to emotions but I can talk... It is like I am protecting myself on the inside while trying to, or functioning, on the outside... (If that makes sense?)
I went through a stage in my life where many years of emotion were numbed out because I went through a few years of a great many people I knew who, one at a time and sometimes days after each other died. I call them my numb years. I was operating like a robot. My Mum and I stopped going to funerals after attending 43 just in a few years as we reached a stage that if I went to another, I would suddenly get a release of all that bottled up emotion and there is no way that I could physically handle it! Both aunts, a close neighbour, both grandmothers (Both grandads had already died), both uncles, my Dad... Many, many people I knew and were close to. It was like the whole world changed for me in just a few years. AAAAAAÀAAH! I feel like shouting at the top of my voice! But I can't. (Why is it the top of my voice? Why not the bottom or the middle of my voice?)
