Hi- it sounds like a very difficult predicament to be sure.

I would start by explaining to him that his failure to share in the household duties as agreed upon is a breach of your trust in him. It is the mark of a lazy dom to neglect his submissive's needs and only exert dominance to get out of doing work.

That being said, marriage does have the effect of changing things, sometimes. It did for me, indirectly. And given how busy you are with all the things you have going on, it might not be a bad idea to officially take a step back from it so that he can breathe and adjust. It's not a fair situation to be in, but relationships are all about caring enough about your partner to occasionally compromise and sacrifice on their behalf.

My initial thought isn't a good way to bring it up to him. You should really try to sit him down and explain where you're at without being confrontational, but still stress how important the conversation is. If he blows you off again, then the next time he tries to play dom to you, refuse it. You're not his maid, you're his wife.

Communication is just SO important. It sounds like he needs to be reminded of that. Wishing you well, and I hope things are resolved to your satisfaction soon!
