In some cases, that “right person” may be another individual with the same disorder who understands and has the ability to cope with the idiosyncrasies of another person on the autism spectrum.
One of my Asperger's clients recently stated that he feels that the relationship with his wife is challenging, in part due to his overwhelming need to focus on his obsession of choice. He feels that he lacks a strong interpersonal connection and has to make a conscious choice to put his focus on his wife, to the exclusion of his desired focus of choice. He is accustomed to being solitary, and he finds it difficult to concentrate with others around him, including his wife.
Unfortunately, the divorce rate among couples affected by Asperger's (i.e., one partner is on the spectrum, and the other is not) is higher than in other groups of people. However, interventions (e.g., marital counseling) can work well if the therapist understands the unique features of Asperger's as it affects relationships.
