Undiagnosed spouse?

I've gradually come to believe my husband has asd and that this underpins our problems. This may sound arrogant, which is partly why it's taken so long for me to speak up.

He finally agreed to raise it with gp but 2 questionnaires later and the gp says there's no hint of asd showing.

This is crushing for me and I'm wondering what experiences other people have had?
