In my therapy practice while my experience is with the general public, for many years, as part of that practice, I've been seeing adults and couples where the main complaint involves the characteristics of Asperger's Syndrome even when the formal diagnosis is not present.
Therapy can help you understand yourself as "different", rather than "rejecting, indifferent or unempathic." This distinction helps to raise self esteem, and changes expectations in individuals, in couples and in family members.
Some characteristics in the Asperger range are degrees of: "having social difficulties", "being a loner", "not good at describing/feeling certain emotions, such as love", "tendencies to being pre-occupied with tasks and particular areas of learning", "having been told in one way or another that you lack the ability to be empathic," "lack the ability to think in the 'grey' areas" and for some it is not uncommon to "feel frustrated that you are not understood" and often are "not understanding what other people mean". Angery outbursts which are really expressions of frustration can be prevalent and cause difficulty relating to others. People who can identify themselves in any of these areas might also recognize one or more of the following characteristics: too insistant, too logical, literal, argumentative and obsessive. This is only a broad overview of characteristics. We are all different and need to address obstacles on an individual basis rather than in categories.
Though recently subsumed into the category of "Autistic Continuum," the term Asperger's Syndrome* has become very popular, sometimes causing us to overuse it. I take a step back from the "diagnosis" to address what is standing in the way of getting more out of life and relationships.
