AIBU to be upset if my bf doesn't always tell me things he's done?
We've been seeing each other for over a year. We see each other every week and message every day. Yesterday he told me in the afternoon he was going to a party with a friend (I have no problem with that). He messaged me this morning and then said he was tired as his friend had been snoring. I had assumed he had gone home, I then thought he'd stayed at his friend's but when I asked he said they had stayed in a hotel where the party was. This meant it was all pre arranged but he'd said nothing to me until after the event. Am I reasonable to feel upset that he said nothing?
