Recently diagnosed myself. Diagnosis only took place because my (now recently ex) g/f told me that I needed to seek some kind of counselling for the fact that I hated socialising. At that time, I had no knowledge of Aspergers.
Spoke to my previous ex to see what she thought, and was rather surprised by the very emphatic YES - I THINK YOU HAVE ASPERGERS.
Oh.
I went to the diagnosis alone - and for those of you who are trying to get your partners diagnosed, that's clearly a mistake. Although I had been made aware of many of my characteristics I'm still oblivious to some of them. The letter arranging the appointment said that if I didn't take anybody, then they'd call someone - but they chose not to. My recent g/f read the diagnosis report last night and although she agreed with the findings in general, she strongly disagreed with a couple of points where they said I didn't display strong symptoms.
While we were discussing it last night, one surprise was regarding routines. Although I am aware I like routine for some things, I didn't think it was a particular thing for me. However - her perspective was that this is not the case at all, and made me realise that my need for routines is less about what I do but more about what she does (or doesn't do). No point going into too much detail but it was basically her saying : You expect me to do every day / week or whatever, and if I don't do it then you feel I don't love you enough, and you get unreasonably upset - and withdraw emotionally. Not only that - often it's something I'd want to do, but because I feel I HAVE to do it, it makes it feel mandatory.
She said one thing that stuck in my mind before she left last night, which I guess sums up how a lot of partners of people with Aspergers feel :
I always knew how you felt. You never knew how I felt.
Despite the above, we seem to be doing OK as friends and she has said she's happy to come with me to some counselling sessions.
This thread is interesting to read - although there are some posts which make me feel one step up from Lucifer - and I thought my (or actually my ex-g/f's view - might add another perspective.
