Need a reality check

My baby is going through a serious sleep regression. For the last 3 weeks, he’s been waking up every few hours at night. But for the last 4 nights he has been waking up every 45 minutes overnight and napping for 45 minutes during the day. I feel like I’m back in the newborn stage and idk how to get through this.

My husband leaves for work at 630am every day. Last night I asked him to be on baby duty so I could sleep since I haven’t gotten more than 45 minutes at a time for almost a week. I slept in the living room (we have a studio so the kitchen is basically in the living room). I am usually responsible for 100% of the night wakings during the week but I feel like I’m drowning so I asked for help. I still breastfeed so he still had to bring our son to me every few hours to eat but at least I could sleep through the random wakings.

At 5am he told me he has to get ready for work and it’s my turn to be on baby duty. I agreed and here I am now, awake with the baby, but I’m thinking why does it take my husband 1.5 hours to get ready for work? He said he was going to start getting ready at 530am and he didn’t want me to have to move over to the bedroom at that point bc it would be too loud for me to sleep with him getting ready and whatnot. But I’m pissed because it should’ve been my night off duty, and I still went back on duty at 5am. Am I being petty?

This man gets to wake up at whatever time he wants and claim he’s ‘getting ready for work’. Aka eating a bowl of cereal and watching tv. For an hour every day. I know it doesn’t seem like a lot, but an hour is a lot when I’m so sleep deprived. I feel like we’re living in two completely different realities. I wish I could have an hour of complete alone time to eat breakfast and watch tv. Meanwhile when my baby wakes up I’m trying to make breakfast and coffee with him in my arms and I can’t even eat for more than 2 minutes before he’s crying for attention. I won’t ignore his cries so I end up eating hours after I wake up and I’m just hungry and cranky.

We went to therapy and the therapist said if this hour is so important to me then I should get an hour of free time in the evening. Well.. I’d like to, but our baby will NOT go down for a nap with anyone except me, so if it’s nap time my husband will try and try to get him to nap but after 15 mins of the baby crying hysterically I just go in and put him down and he’s asleep in seconds. Also, I EBF so it may be feeding time. Last night I tried to shower and my husband kicked me out of the bathroom so he could poop 😂😭😭😭

I’m just at a loss. What can be done?
