I have aspergers. The thing I loved the most when dating was handwritten notes rather than texts all the time. And if apart, then texting was fine but with lots of emojis (it was kisses back then though!)
I felt like texting was difficult to read the tone and often I'd take it in the wrong way.
My lovely bf, now DH of 16 years wrote me little post it notes. That made my heart do fluttery backflips. He still writes me little reminders on the whiteboard. I love them. I've kept them all from our university days!!
My main outward aspergers trait is that I take things very literally. I'm 36 now so it goes a bit like this
DH: says something silly
Me: Take it literally then a second later I realise it's a joke. Then another second after that, I laugh at my initial shock face reaction
Both: end up laughing.
Cuddling is so important to me. But if DH is wearing a specific knitted jumper - I can't touch him. It gives me sensory overload.
Sometimes I find general noise too much and can't focus on people talking to me. It looks like I'm not listening or ignoring them. I don't mean to.
Ask him to be honest when he's overwhelmed.
OP you sound so lovely, thoughtful and patient! I wish you two the best of luck and lots of happiness x
