2. Cheat
First of all, cheating doesn't always ruin a relationship. For some relationships through hard work and commitment from both persons, it draws them closer together and strengthens the relationship. Obviously I'm not saying if you want your relationship to be stronger go cheat!! But for others, the fact that their partner cheated is a blow that can never be recovered from. Some people cheat and are forgiven; but they continue to cheat nonetheless, just being more careful not to get caught. If you want to indulge in that kind of behavior, you shouldn't be in a relationship.
3. StealWho wants to be in a relationship with someone who steals? money from his wallet, her purse, etc. Apart from for being paranoid all the time that he/she is stealing from you .. AND lying about it. You're supposed to feel safe in a relationship. Safe with your emotions, love, and belongings. Stealing from your partner is low down invasion of privacy, and blatant disregard for their belongings. Why would anyone want to be with anybody who is like that?
4. Keep secretsthis goes back to my point earlier about trust in a relationship. For a relationship to survive, prosper, flourish. There needs to be trust. Keep secrets and there will be no trust. If you don't want to keep secrets, don't indulge in any kind of behavior that will offend or hurt your partner. And if you do, be honest about it. Never give that "other person" the power to ruin your relationship by making them privy to your secrets and your partner is not. That my friend, is the DUMBEST thing you could ever do.
5. Flirt incessantlyLet's say you arrive at the club, only to see your partner's mouth in someone's ear, their bodies not inches apart. Now stop. At this moment, it doesn't matter what's being said or who it's about. The fact is.. they're way too close and you don't like it. Their body language to you says nothing "innocent" is happening. If you're hurt by this, offended or even jealous. How dare you do the same thing to them? People like to make the excuse "I was just being friendly" but if you ever acted the same way they did, you would never hear the end of it. Flirting leads to sex, cheating, etc. If thats what you want then fine go ahead. But not if you are in a relationship. Your actions should speak for themselves whether or not he/she is around. And if someone is getting touchy feely with you while your partner is across the room, whispering in their ear "my partner is over there" doesn't say you want them to stop. It says to them, its fine for you to do it but not while they're here so I don't get in trouble. Choose your words wisely! Learn the difference between "friendly" and "flirty" and act accordingly. If not, it could cost you your relationship.
