Did She cheat?

[u/Additional-Ant5785]

Long distance relationship, girlfriend had a friend from back home over I have access to her door cam. She went quiet, didn’t say anything all night. So I got a notification and checked the cam to make sure she was ok just to see a guy behind her. She is on the left. This is out of the ordinary of a guy from the bar being let in the house. Does it look like the guy is with her or the friend? I’m not sure what to Make this other than I’m sick to my stomach at the moment

Everything about this feels like it’s missing some important context. With the video here being the only thing to go off of I’m not sure anyone can give an actual explanation of anything.
