Congrats on your pregnancy!!!
I would suggest, if you know that him being tired is the trigger for the emotional outburst. Then avoid him like he's the biggest epidemic whenever he's in that state. Sounds extreme but you get what I mean.
Men are wired differently from us. If they're tired, they may prefer to have some time alone, either to space out or do some menial task. The fact that he's assisting with household chores when he's tired is already an act of love for you. To ask for more by seeking his attention is like entering a lion's den waiting to be slaughtered because they do not have the bandwidth to cater your feelings.
The next time you sense a storm coming. Stay clear and do something happy for yourself, read a book or watch TV. Do that until the storm blows away.
Happy Mummy = Happy Baby
