2. She threatens to break up every time you have a disagreement
Partners who are masters of manipulation will constantly use the “break up” card at their disposal. If you don’t do what she says, it’s over. If you don’t think the way she thinks, she’s out of here. It sometimes makes you wonder if she’d rather be single. Or at least with another guy. These arguments aren’t spurned by issues like you acting irresponsible either; she demands that you forgo other commitments — including those related to your career —because she is jealous that you would devote time to anything but her.
