From my personal experience with living with a husband for 33 years whose behaviors perfectly fit Aspergers (ASD), the symptoms do progress & show up more the older he got. Though looking back at dome of the things his mother said sbout him has just fit right in. The red flags I saw before I got married but excused away are EXACTLY the things I finally left because only magnified by 33 years of living around it. When I left it became all that more obvious because then he had no one but himself to depend on & he royally messed up his life while financially destroying mine also...but it showed how much he had been depending on me to keep his life out of the mess he is now in...i was seeing it more & more the last 13 years when massive depression left me non-functional...but it was cast in concrete when I finally left. He got along thoygh always had problems communicating in his computer engineering career but the more demands that were put on him the more dysfunctional it was obvious he was....so late-onset only serms that way but when seriously analized it does show up much earlier
