I'm Asperger's too and my good lady and I have been married 36 years. After a few rough early years of not knowing why I was the way I was, we both figured out I needed time alone, and she needed time together, and we balanced it out. We only really understood where I was coming from after our son was diagnosed with Asperger's in High School, and boy it explained a lot about me too.

As everyone else has said, you need to work at marriage, but knowing ahead of time where you are both coming from should let each of you avoid unrealistic expectations about the other, and be supportive of the other's needs.
