So I was on FaceTime with my boyfriend and I was tired so I said I was going to go to sleep. So we said goodnight and I hung up. After like 15 minutes he facetimed me again saying he didn't feel good and that he threw up. He was crying, all of the sudden he started breathing funny and then things went dead silent. I tried to say his name but I got no response. Then the call ended. I'm really worried something happened, I would call the his house but it's the middle of the night and I don't want to disturb his family, especially if he just fell asleep or something. I just feel it was too abrupt from when we were having a conversation to where he just stopped talking. I tried to call him and text him saying I was worried because he suddenly just stopped talking. And if he decided to go to sleep he would have said goodnight. I'm just not are if I should call his house, like what if he just fell asleep? Idk what to do but I can't sleep now:( please answer quick because I don't know what to do right now

Crying ( does he normally cry) breathing funny,

Yes you call his house, he is was acting silly to upset you, he needs to learn that was wrong, and a call to his house will do that. If something is wrong, they need to check on him
