DH messaged saying he was going for drinks after work, and would be back about 8 or 9.
At 10.30 I messaged asking where he was, no reply. Tried to phone, 45 minutes later he replied saying "missed call will be leaving after this drink".
I woke up at 1.30am and he still wasn't home so rang him a few times, no reply but he came online on WhatsApp so knew he was fine. He got home at 3am and doesn't think he did anything wrong as he shouldn't have to tell me if plans change.
AIBU expecting at least a simple message saying "I'll be back later than planned" or to answer the call when he's on his phone anyway.
