PMSL winny - you made your husband sleep in the hall!
At 13 weeks he is only just able to go through the night, so try taking him out and staying out with him later, give him his last feed a bit earlier, and make it a milky one rather than solids. Confine him in a puppy pen or cage, or in a corner of the kitchen and give him some newspaper to go on if he has to. Set the alarm a bit earlier and get up to go out with him. If he is only weeing during the night, he is ok to leave, so don't go back to him if he is crying, or you will never stop him crying.
Personally I would use a cage and give him some toys and chews to keep him amused.
