I would suggest trying to swap from morning raiding to evening raiding. I'm a single Dad with a 15 month old, had him on my own since he was 2 months old BUT still managed to play WoW in the evenings and do some casual raiding as well....but when he was asleep. I think the issue does seem to be more with your relationship than the game. Spichora above me i think has got it nailed on. Hell, as a single parent i deffo need a couple of hours to myself every now and then.....alas, not to WoW anymore, just cancelled my sub lol
I think if you swapped to a evening raid...you may find your husband a bit more forgiving, however that may only be papering over the cracks
