My husband thinks I’m stupid....

My husband has a terrible lying habit. He lies about EVERY THING, to everyone.

Stupid things, big things, you name it! It drives me absolutely crazy. He thinks I have no idea, but he is dead wrong. I’ve tried to confront him about the things he’s lying about and he will deny, deny, deny. I’m at a loss here. I can’t take the lying anymore and I just want to pack up my kids and leave! I suffer from depression, so I don’t know if that’s too irrational. He won’t accept help because he says he isn’t doing anything wrong. “No one needs to know my business” he says. I feel like I don’t know him because I don’t know what’s true and what’s not. I’ve talked to my therapist about it and she says to confront him but I have and it just doesn’t work. It ends up in a huge fight. I’m angry and hurting. What do I do? 😢
