He is anxious & also has autism.
We were estranged for 10 years as I couldn't help him & it was impacting on my parent's health (one of them has died). Only starting to get close again.
Since we've started to become close again I just had to tell him
A) if you swear about this particular problem that will automatically devalue what you say & they won't listen to you
B) it is a genuine problem but if he swears noone will listen to him. He also has tourettes.
So should I have said something else? He'd calmed down by the end of the conversation
