Divorce rates are climbing all the time, and the number of Aspies in these figures, wouldnt even rate. Long term relationships ships are hard work and the NT world are having just as many problems as us. The clear difference is when you have a diagnosis of a condition, its very easy to assume thats why a relationship is failing. We may have issues communicating and supporting our partners, in the way they want, but obviously so is does the rest of society. It really comes down to what each of us wants out of our relationship and communicating those wants. Unfortunately a diagnosis is a convenient excuse for not working at things sometimes. And that goes both ways
So essentially what it comes down to, is that (presumably) too many people go with a single approach that might work to some extent for a lot of people, but clearly not all people. Just because in your previous relationship, or your friends relationship, it worked out so fine. Perhaps some people are way too rigorous in their problem solving skills when it comes to relationships... and they call us aspies rigid thinkers...
