I have a relative who now lives in Germany who I haven't seen since June last year. She's come home for the weekend to stay with her parents. I asked DP if he'd watch my 2 DC's 9 and 7yrs(DC's from a previous relationship) for an hour so I can have a quick catch up with her as my DC'S didn't want to come with me and DP needed to stay home anyways catching up with paperwork. He said that was fine. Last thing I said to him before i left was to call me if they started playing up and I'd come home and he said ok.
I came home and asked if everything had been ok and he went on a 10 minute long rant about how they'd be arguing non stop for the past 30 minutes and that he'd got no work done because they were yelling at each other. I said why didn't you call me and I would have come home and he just shrugged and said "I didn't want to bother you"
AIBU for being pissed off that he just didn't pick up the phone and and tell me they were misbehaving, he knows I would have come straight home to deal with the situation instead of complaining that they had been misbehaving.
