I think it might be (g) as well- we don't know what it is. Perhaps if he's been on the phone to his Mum he feels drained and doesn't want to talk any more tonight. I know my H is like that, so there was never any point trying to initiate a conversation immediately after he'd been on the phone to his Mum (or anyone else for that matter).
Be still and back away from him. Let him sit in his cave and think while you give yourself some time to heal a little. He WILL get in touch.
