Why did he let me sleep in his bed?

So my boyfriend and I got into an argument a long time ago and I went to his best friends house to clear my head. We are mutual friends with each other. It was really late when he picked me up though, like 1am late, and he had his friend over too.

He ended up letting me sleep in his bed while he took the couch. Any reason why he let me crash on his bed after I got into an argument with my boyfriend? He didn't try to sleep with me or anything but he let me use his blankets and stuff. Just wondering if that means anything or not.
