I went out with an undiagnosed aspie for a bit. ive done loads of reading on it, not sure it's helpful to quibble with diagnosis firstly, maybe we should take op's "it just clicked' at face value. I remember reading that in some instances dp's end up with ptsd and that there is very little research done on the effect of being married to someone on the spectrum, everything is focussed on the autie.
Doing "loads of reading on it" doesn't make you an expert though, nor does it make you qualified to decide if someone has Aspergers or not. And gee, imagine that, most of the research focusing on the person who has the actual fucking disability.
And unless you have autism or Aspergers don't use terms like "Aspie" or "Autie."
You encapsulate one my pet hates, that is women who decide that their partner has Aspergers because he behaves like a jerk/is antisocial/is blunt and rude etc.....
And then spend all their time whining about how awful it is to be with an "Aspie." Without of course actually knowing if their partner really is autistic. But no, sure, you can tell because you "read loads about it." 
Your advice is insane, for what other medical condition would you tell people not to "quibble about diagnosis?"
No, you're right we should leave it to people like you to decide if someone is autistic or not, since you think reading a few books and internet articles is enough to know if someone is autistic or not.
If I found out my husband was Asperger it would give me validation that no matter that some of his lacking social skills aren’t personal and that he loves me in his unique way.. it’s not a reason to leave someone you love, but instead starts giving you an explanation. I feel sad that you are holding his diagnosis against him. You can say you can’t cope with it but that’s not his fault?.
Can people not even read the opening post before commenting? She's not holding his diagnosis against him because he DOES NOT HAVE ONE. He took a screeing test on the internet, that's not a diagnosis for god's sake. And once again, a person cannot "be Asperger." You have Aspergers, no-one can be it.
