That's another way to say, "I'm going with someone else".
I could be a door guard or a repair man and still be the guy having sex with the person's spouse. It doesn't work like this all the time, but who knows how bad she feels sorry for this guy. His intentions aren't just appearing out of the blue. That's like asking a stranger to drive your wife home while he stops at his hotel to gather a few things. It's going to raise suspicion either way you look at it. A kiss, a hug, a grab, and then what's next? They're having sex behind OP's back.
He could be allowing another man to enter her life. Sure, women don't always cheat, but there's a large percentage that do do this.
The bold is irrelevant if the guy is already a friend. He's not a stranger.
The first part you're still not getting. Say a friend from work asks you to join him as a +1 to his brothers birthday or something. YOU don't get to just take another friend with you, you are the +1.
