DH is taking the kids out in his own this morning, he doesn't usually do this. As he left I said "do you want to take the kids' drinks?", he replied "I was going to buy them drinks there" then as he was closing the door with his back to me I saw him shaking his head. This has really annoyed me! AIBU to be annoyed by this? I was just trying to help. I see him do this to his DM all the time, basically saying "what an idiot / nag / etc".
For context, we are not getting on well at the moment because he is going through a tough time and has some MH issues which he will not address and instead blames his problems on me / the kids / work / the house. Don't want to get into all that, just trying to decide if I'm over reacting to the head shake by unfairly being annoyed! Thanks
