People who gaslight typically use the following techniques:
3. They use what is near and dear to you as ammunition.
They know how important your kids are to you, and they know how important your identity is to you. So those may be one of the first things they attack. If you have kids, they tell you that you should not have had those children. They will tell you'd be a worthy person if only you didn't have a long list of negative traits. They attack the foundation of your being.
4. They wear you down over time.
This is one of the insidious things about gaslighting—it is done gradually, over time. A lie here, a lie there, a snide comment every so often...and then it starts ramping up. Even the brightest, most self-aware people can be sucked into gaslighting—it is that effective. It's the "frog in the frying pan" analogy: The heat is turned up slowly, so the frog never realizes what's happening to it.
