Just back from city break with DP. We had a very early flight on the way out, had been awake since 2.30am. We went out exploring all day and had dinner reservations for 8.30pm to celebrate my birthday. We had a few daytime drinks and inevitably I was tired. For context i am known for falling asleep earlier whereas he copes on little sleep. We went to the hotel at 5pm and I planned to nap for half an hour but we both slept through for 3 hours. We still made dinner but DP gave me the silent treatment for entire night, said about 2 words to me and sat with his face like thunder. Afterwards he said it was because it was my fault we fell asleep for hours and he couldn't enjoy his meal half asleep.. We both fell asleep and I think is reasonable given the time we were awake. I feel that he ruined my birthday meal and was trying to punish me but he doesn't see that. Do you think he is being reasonable here and just to let it go?
