Having a hard time ...

Is it normal for the mama to do most of the work? I am up throughout the night with the newborn and then I wake up (from like 3h sleep scattered) at 7am with my 4 year old while boyfriend just sleeps through it all and awakens when he wants. He then is off going to the gym doing whTever he wants. Like tonight he is off to a concert. Is it wrong to think maybe I deserve the break more than him? I mean i was pregnant for 9 freaking months and I haven’t been able to get out of the house with my friends and just enjoy me yet HES GOING OUT? Can’t help but feel a little envious and worn out. :( I mean I love my babies soooo much!!! But is it normal for moms to do basically everything while oh helps sometimes? 😓
