So last night my 16 yo step son stayed the night for the first time in a few months. We were at a football game and didn't get home until about 10pm. Everyone was in bed by 12am. His dad/my fiance went to work at 7am and my step son got up at 10am and went home at 10:30am. I let his dad know right away and immediately I was blamed for him leaving early and asked what I did. Accusing me of making him stay in his room and be bored so he would go home. It ended up being a huge argument between us and finally he realized I did nothing wrong.
