I've NC for this one.
DH and I have been together for about 18yrs and have two small children under 4.
DH has difficulty with communicating and I no longer have the patience or headspace with him for it, it's driving me insane.
He'll start a conversation with a single word and assume I know the rest of the information intrinsically. E.g. "photo". Then he'll slowly build up from there with guiding questions from me:
DH "photo "
Me: "Pardon?
DH: "you know that photo "
Me: "What photo do you mean?"
DH "Passport photo"
Me "Oh you need a new passport photo then?"
DH "No we can use one we already have."
Me "Hang on, you need a passport photo for something?
DH "yeah my parents"
Me "so your parents need a passport photo?"
DH: "no not them"
etc etc
Then we go around in circles for about 10 minutes like this until the almost full information is shared and it transpires that he spoke to his parents 2 weeks ago and they have signed up our child to something or other without my knowledge and require a passport photo to complete the application which they have been chasing DH for because it's been 2 weeks since they asked for one.
This is how all conversations end up these days and I just don't have the patience for it any more with 2 small children and me as the default go-to parent.
The analogy I would give to explain it is an alphabet one: he starts at z, then with probing he'll return to d, back to a, skip to s, return to u, back to m, miss out n, o, p and then land at y when really he needs to start with a, then end at z.
Where can I point him towards to help him understand / learn how to effectively communicate!?
