If you're constantly in the dark about your partner's plans, and they are always trying to convince you that you're just forgetful, this is a sign of gaslighting.
If making your own decisions has become an issue, it could be due to your partner undermining your self-confidence or attempting to lower your self-esteem.
You should be able to talk to your partner about your concerns, but Lawless says, "Cheaters may try to gaslight their partner by insisting they are paranoid."
