DP and I have recently moved in together. There's a general "dumping ground" side table where we leave keys, change, lighters, cigarettes.
Yesterday I had no cigarettes and took a couple from DP's pack when I was leaving the house to last me till I could get to a shop later (long morning commute, no time to stop on the way).
Absent mindedly, I accidentally lifted the pack along with my keys on the way out the door and didn't realise until I received a text from DP asking if I'd seen them. I apologised and explained but he was clearly a bit annoyed though he made light of it at the time.
When he got home he claimed he hadn't had a cigarette all day, which I challenged him about as usually he would make it to one of the several shops he passes on his way to work. He still said he hadn't had any cigarettes all day.
I checked his pocket and there was a pack in there with several missing, so he was lying about not having any. I haven't really spoken to him since last night and i'm not sure whether to let this go or to bring it up again. He is not usually a liar, even major issues he is able to be honest with me so im not sure why he lied here?
It crossed my mind that this may even be gaslighting?
What do you think? AIBU to worry about this?
