I'm actually feeling very unsettled now. This morning he's approached me twice (I am working in the home office so not in his way or getting in his business - he has a day off shift today) and said he'd bought some presents for Youngest's birthday. He told me what he'd bought and I said, 'I think she'll like those things' then he rolled his eyes and said, 'only you know, I have to be very careful that you won't go mental if you don't approve,' - I made a listening noise and went back to my work. A bit later he asked me which friend I was seeing tonight. I'd told him this this morning - when we were planning the day and who would care for Youngest in the evening - and I said, 'oh, it's Avril' and he said, 'yes, you said that this morning but you had to think about it a long time so it sounds like you're making it up.' I think he's desperate for me to defend myself so he can have the argument he's looking for, so I just made another listening noise and turned back to my work. He's on his computer now very ostentatiously looking for two bedroomed flats to rent.
I literally have NO IDEA what is going on with him, but am determined to be calm and not engage and take care of myself. I do feel very anxious about what he's going to do to escalate now it's clear he's not getting the response he either dreads or expects or wants.
