6. You accuse her of checking out a guy.
“You were checking him out, weren’t you!?” You always get paranoid that if she looks at something other than you, she’s checking out other guys. If you do this, she’ll get flabbergasted at your accusations and fed up with having to defend herself. If you’re that curious about where her gaze is directed, be straightforward and ask her, “What happened?” That way, you don’t sound accusatory and she won’t be offended.
