Bad people use the feelings of others to get what they want. To get you to stay, they'll say horrible things, even to themselves, and make you believe that if they do them, it will be your fault.
When everyone you know has had bad experiences with someone, you can probably assume it’s the person and not everyone else.
They'll start with small things that don't seem important and say things like "they didn't know" or "didn't think you were serious." Watch out for people who cross even the smallest line.
Too many of us won't believe someone when they tell us straight out who they are. Trust them when they say they're not ready to commit, aren't sure about the relationship, or don't know what they want.
People who constantly and easily lie to everyone else are probably lying to you, too.
That person who says you can't be friends with people of the opposite gender probably likes being in charge. It's even worse if they don't follow the same rule.
If they’ve cheated on all their partners and openly admit it to you, they’re probably going to cheat on you, too.
Insecure people will do anything to make everyone else feel less than. They’ll nitpick you, sabotage you, and undermine everything you do.
You can tell a lot by someone with how they act in a minor conflict. Do they take responsibility for their behavior, or do they run?
Every once in a while, we can all enjoy some toilet humor. But when they can't find any other funny things to say or are too busy making inappropriate sexual jokes, they probably only have one thing on their mind.
If you have a weird feeling in your gut, listen to it! Our instincts were honed over millennia of evolution. They’re unlikely to lead you astray.
