Don’t go around flirting with someone who’s taken, don’t even try to homewreck. It’s very shallow and disrespectful. They’ve gotten to where they are in the relationship from a long way and have been through so much, so they don’t deserve the extra bullshit coming from you trying to ruin their relationship. Flirt all you want, but with someone who is actually single. Yes it’s okay to keep in touch but know your limits. Trust me you wouldn’t want that to happen to you. Don’t be a bitch. Know where you stand. Learn to respect others and their relationships.
