Like flipping a switch, he can change drastically from one extreme to the next. He or she acts one way when they are around you, but completely different around your parents, and completely different around their friends. Slowly, you lose your friends until you feel like your partner is the only person you have left. Your partner cycles from mean and vicious to sweet and loving, then back again. He might set traps for squirrels or rabbits and then torture them.
It seems like your partner is two completely different people. Your partner finds faults with your friends or makes you feel bad or uncomfortable about any time you spend with other people. You want to believe that this is possible, but the cycle keeps repeating and each time your self-esteem is chipped away at, bit by bit. He might hit or kick your dog whenever he comes over.
I, for one, have chosen to live life on my own terms.
Here are some signs that might indicate that you are dating a psychopath. You might get mad at people for trying to convince you to break up with your partner, or make excuses for your partner because you are convinced that you are the only one that understands him or her. He or she feels entitled to act the way that they do.
Just a little at first, and then slowly your doubt spreads.
