Do not flirt when you're in a
relationship. Just don't. I mean if you're in a relationship, it's not cute or funny in any way for you to go off and flirtwith someone else. You're with someone who is possibly hurting or jealous, because you go off and do
such things. Sometimes, this person you're with will say it's okay, but it's because they put up with it, only because they adore you to pieces, they love you a lot, and they don't want to lose you.
