<human>: We've been together a year. We were in bed at his house, and I could not sleep at all this morning. I woke up around 5 to pee and could not fall back asleep. My boyfriend was getting upset because I was using my phone to pass the time, and at one point said  " you're done using your phone". I said sorry and tried to fall back asleep, but I just couldn't and looked at my phone again and he got mad and said he was exhausted because of me. I set it to lowest light so i wouldn't interrupt him. So I figured the best plan of action was just to head home then (7:30) so he could sleep before work and I could get ready for work at my house (2 miles away). I said "I love you and ill let you get some rest" to him and he said love you too. I think he only realized I was going till he saw my clothes on and told me I didn't have to leave. 

I tried to explain that I couldn't sleep and I was just going to get ready for work early because I was up and I didn't want to keep him up. He got pretty mad, and when I was outside he shouted out the window " I can't believe you're actually leaving", and again I tried to explain to him that I'm not mad at him, I just don't want to interrupt his sleep. And he said " just lay back down for another hour". I didn't really feel like getting yelled at for another hour and not at least being productive while I was up, so I told him " I love you, I'll see you tonight!" He was just like WOWW, and shut the window. Then I get a call from him telling me to come back and saying how I can't believe you left, I didn't know how to explain it any other way :( then after I tell him sorry he texts me and tells me we're drifting apart and he'll see me *sometime*... Reddit help me understand this please .

Can you summarize the given text in a few sentences?
<bot>: I couldn't sleep this morning so I went back to my house early so my boyfriend could sleep, but now he's angry at me and isn't accepting any explanations*
