I may be way off the mark here and I am quite ignorant to autism spectrum disorder so jump in and correct me please.
I've got to know my bf for over a year now.
The issues that keep coming up for me are:
He never asks any questions, so eg yesterday we met for a walk and I ask did he have a good Xmas then? He answers and that's the end of the convo.
I've noticed this for a long time, he will answer the question and not use that as a bridge to then ask me something similar or ask the same back.
He is in a routine and he is adamant he has to sleep in his own bed. So he will make excuses and there was even one time he went quiet for hours because I said i wanted him to sleepover at the weekend. I believe this was because he was stressing that he wouldn't be in his own bed.
He also has an inner routine as there were occasions where I saw him on 2 consecutive Saturday nights.
The first one at 9.24pm he texted saying he was leaving to come over.
Then the next week at 9.24pm he texted the exact same message. I checked this as I had a chuckle to myself that I bet it was 9.24 last week too and it was and the same wording. Both times he was leaving between 9 and 10 to come and he would let me know when he was leaving.
He cleans up after himself immediately, so he has dinner then goes straight in to do dishes and tidy up. (not complaining here but seemed unusual!)
His texts are all of a similar nature and I can usually predict when he will text and what he will say.
In summer he was working away and we were fwb at this point. I casually said 'give me a shout the next time you are home then'
He took this literally as I didn't want to hear from him until the next time he was home. As in he made sure he didn't contact me until then. He explained this to me after.
I've mentioned a couple of things I'm worried about or that have been stressing me, he never once has asked how I am and how I'm coping with said things. Everyone else in my life would ask how such and such is etc
He will buy the top most expensive equipment for different activities even if its not something he regularly does eg hill walking, fishing but he is a bit fixated on buying all the right kit and having it all.
He said sometimes he will be ready to go out somewhere and then go and completely change what he is wearing because he doesn't feel good in it.
If I ever challenge him on anything (I mean an opinion on something) he goes into himself and feels attacked
He can be very quiet at times and very withdrawn at times.
He does not talk about his feeling at all and if he's pushed he becomes very uncomfortable.
He has funny accent type things and funny facial expressions that he does all the time and I think he will do them as a defense technique when he's feeling uncomfortable
He's never said anything like 'I'd like to take you here' 'I'd like for us to do X'
He said he spent years deciding whether or not to buy a winter jacket he was looking at.
All in all he's a kind person, he's definitely lacking the normal social skills that I'd expect of a 40 year old man. Some things are so odd to me I've never experienced anyone like this before and this morning I'm just wondering if it is in fact autistic characteristics and this would maybe help me understand what's going on here.
