David is probably having wild swings of emotions himself. Confused, scared, unhappy. No telling what he's going through.
Don't make yourself an easy target for him and the consequences he must now face.
If you make yourself an easy target, then he won't have to face the consequences of his actions. And it'll be all too easy for him to take out his 'stuff' on you. If you aren't available to be blamed for his stuff...he may just have to face it...by blaming you, he's still running away from facing it. Don't make it easy for him.
