We can’t tell you what to do, luckily though, outside of emotional attachment, you have no further ties. If he’s insistent on lying to you and cheating I’d get rid. If he came to you for help to stop, and you came up with a plan together then I’d say give him a shot, he’s not though, he’s cheating, lying about his addiction and god knows what else. Move on and find someone who respects you.
