how do i get over the anger?

Now knowing that my husband's "neglect" is a by product of adhd, I get its not on purpose but it doesn't matter. When his therapist first mentioned he suspected my hubby had it I thought "ok then we will fix that and it'll get better." I didn't understand what all adhd had impacted so I read about it and heard my own story being told over and over again. I thought "this really isn't his fault or intentional!" I just keep waiting for this anger and resentment to go away and it doesn't. Does anyone have any advice on how to overcome my anger towards him? He said he resents me for my anger towards him and its noticeable because he finds ways to avoid me.
