<human>: He has been ignoring me for the past 13 hours and I don't know what to do. We were texting last night and everything was fine. When he stopped texting me I assumed he fell asleep on the couch. I sent him my usual good night text and went to sleep. Usually when this happens I will wake up at 2 and find a good night text from him, too. Well, when I woke up at 10:30 this morning he still hadn't said anything. No good night or good morning. I figured that when he woke up from the couch it was late so he didn't text me good night. I sent him a good morning text and continued my day. 

Now, we usually go to bed and wake up at the same time so I was getting really weirded out when he hadn't responded by 11:30. He doesn't usually sleep in so late and if he had had to work in the morning he would have texted me good morning. I sent him another text seeing if he was there. After an hour of no response I called him and got voice mail.

Frankly, I don't know what the hell is going on. I thought everything between us was fine considering the last message I have from him is "I love you so much." But I'm getting really freaked out. This isn't like him at all. What should I do? He's obviously ignoring his phone and I'm starting to feel sick with anxiety.

Can you summarize the given text in a few sentences?
