It depends on the person. Some personalities tend to "click" more than others, regardless of labels. It's all about how well you and the other person get along and are friends with each other, first and foremost. My boyfriend is NT, but he's very understanding of my ASD traits, plus we have incredible interpersonal chemistry.
With that said, I know more AS/AS couples in happy/successful relationships than AS/NT relationships. One couple I know has been together for 5 years.

Given a “tentative” diagnosis as a child as I needed services at school for what was later correctly discovered to be a major anxiety disorder.
This misdiagnosis caused me significant stress, which lessened upon finding out the truth about myself from my current and past long-term therapists - that I am an anxious and highly sensitive person but do not have an autism spectrum disorder.
My diagnoses - social anxiety disorder and obsessive-compulsive disorder.
I’m no longer involved with the ASD world.
