The person who keeps saying you’re the problem in the relationship has a secret.
There’s a reason why you keep apologising and trying harder, yet still get it wrong. Calling you too sensitive, accusing you of overthinking and refusing to discuss things? That’s a deliberate tactic.
Because you’re not really the problem – and they know it. When they call you too much of something, it’s because they’re not enough of it. They don’t want you to think too much because they don’t want you to notice what they’re doing. Making you feel guilty keeps you focused on their needs, not yours. Refusing to talk about things keeps them in control.
They can’t match you so they need to shut you down.
