I was being friendly to this guy who's in a relationship. After a few days, I read posts from a social networking site stating that she's in a bad mood and stuff about someone trying to flirt with his boyfriend. I am starting to think it was me, and becoming paranoid about this issue. I don't want to interfere with their relationship, but someone's misunderstanding it. I can't stand feeling like crap now. -_-

Let both parties know you were just being friendly and not flirting. Problem solved.
