Communication is a problem with most with Asperger's. Being in a relationship is even more problematic, sometimes. I found this perspective from a Yahoo Support Group to have it "right-on", in terms of what it is like to be in a relationship with an Aspie (as one with Asperger's, is so affectionately called)
I ♥ him!!! He is great anyhow! lol
For a Successful, AS/NT marriage (Asperger's Syndrome/ Non-Typical)-
"communication can be very rewarding, but it does take a great deal of effort.
As an NT I speak "duck". Being in an AS/NT marriage I've had to learn to translate my duck into AS 'goose', then the goose response needs to be translated back into duck so I can process it, then myNT/duck thoughts must be translated into goose - on and on like that until both AS goose and I, the NT duck are on the same page, or at least in the same book - sometimes the same library will have to do"
