I guess it's a boost of motivation for both of u and u need to have a heart to heart talk. Maybe when u r frustrated, its easier to speak words that would hurt each other instead of resolving, which would escalate to further emotional strains. Meet him at a time u both are more rested and talk amicably. I am in the same situation whereby my hubby lost his job and is now doing food delivery and some days he is more tired than usual cos he have to go thru rain or shine, on a motorbike. I understand cos I ride too and sometimes when I get exhausted I feel like snapping but instead I find the right time, I put on my pitiful face and talk gently telling him my frustrations and also how it would be if I can't provide good care to my LO if i am affected emotionally due to exhaustion and stress on financial and stuffs. Tell him u appreciate him and remind him its just small favour on a bit of teamwork, just maybe waking up to do milk, only mornings and the rest of the day u wil handle, then help chores abt 15 to 20mins of his time, cos teamwork really makes a healthier rltnshp btw couples.
But for me, after years of being together, I always tell myself whenever my husband is not able to wake up or help ard, I am still able bodied so I wil do it instead of grumble and things get doned well, and I am happier and at times, it just happen that he wil automatically be hands on again. Hope ur situation wil get better soon dear.. Strong momma. Ur LO wil be very proud of u and ur strength.
