Micro cheating is cheating. If you're talking to someone else without your partner knowing, then that's cheating. If you're going out with someone who's not a friend or not blood-related and your partner doesn't know, that's also cheating. If you're joking around with someone in a flirty way, that's cheating too.If you're flooding someone's inbox with messages without your partner knowing, that's cheating as well, especially if you're deleting the conversation because you don't want your partner to get mad. Well, that's also cheating, darling.
