My lack of memory affecting marriage

I have so little autobiographical memory. My husband remembers ever & remember hardly anything.  The result of which is that he can remember everything I have ever said or done wrong and I can't remember anything he has done of said wrong. 

He says I have changed since my diagnosis and I am using my autism as an excuse for my poor behaviour.  

I have no idea if he is correct or not but he makes it feel like everything is my fault and his unhappiness is due to me.
