I offered to post an item on my husband's behalf on facebook marketplace. We agreed for the item to be picked up at particular time. After 2.5hr the buyer was still not there. I wanted to go to bed so told my husband to wait (since it was his item and his money). He started getting annoyed (understand that) but raising his voice at me even I was doing him a favour and dealing with all the communication etc.
Anyway the buyer came eventually but didn't have cash and didn't apologize for being late. I was annoyed at that point as well so didn't go to bed.
I don't blame him to get annoyed about the situation but I blame him for raising his voice at me (it wasn't my fault after all, the buyer kept on saying they are coming and just delaying the timeline further). AIBU to be pissed off at my husband for raising his voice at me?
