I am not sure whether it is a guilt feeling. My W did not fix anything when she planned to leave. What your H is doing seems so illogical if he really plans to leave.
May be other LBS here can confirm whether their H did fixing before leaving. I would think that your H is feeling comfortable and not planning to leave any time soon like In4Ride's H. Just act as if and don't ask about his plan for the moment. Continue your relaxing time together.
