Am I being unreasonable? Frustrated intern fiancée here

My partner and I are set to get married this year. He has a very demanding job (PGY-1) and I work from home. He gets maybe 4 full weeks off a year and days off in throughout medical rotations.

Because of his job, I’ve taken on most of wedding planning. I also take care of most household chores in addition my FT job, studying for the LSAT, etc.

This week because he’s off, I thought it was a good time to delegate some wedding tasks to get done so I can focus more on studying. He was tasked with having names printed on envelopes and sending two emails, that’s it.

We got into an argument yesterday because he feels like his to do list is never ending and he’s frustrated. He works a lot of hours, gets a lot of feedback and just wants to unplug. I understand that he may be feeling some burn out.

The wedding tasks he was assigned, he’s delegated to his mom. This would be fine, however, this isn’t the first time it’s happened. I truly cannot say with the exception of a few emails, what handy work he has done to help with the wedding.

His mom shared with me yesterday that he just needs a few days to play “hooky”, relax, not talk about wedding stuff, and do nothing. That he needs his alone time and not have things to do.

I told her this is fine, but he needs to communicate with me when he’s feeling burnout so I can be supportive. She goes “he’s not going to tell you. You just need to feel it from him. Men don’t operate that way, they need to feel wanted and useful. Give him the rest of the week with no tasks, no household chores, etc. Oh, and I know you’re on a no sugar diet but for the sake of today, drink the boba tea he got you. You can start again tomorrow or when he goes back to work.”

We’re supposed to be married in three months. I’ve put my studying on the back burner to plan this. I don’t get a week off every three months, lucky if I can get it at the end of the year. But I’m expected to continue to do everything because he’s f@@king tired and this is his week off?

I’m worried when we have kids. What does this even look like? If we can’t collaboratively plan a wedding now without him getting super overwhelmed with this and work, wtf are we supposed when we are parenting and working?

I don’t want to dismiss his desire for a week of rest, I get it. I get that everyone wants to chill on their time off. But I’m also exhausted, too. Millions of people also have stuff to do, work, kids, obligations, etc. We don’t always get multiple weeks off in a year to just chill. We are so close to the wedding and there is so much to do.

I don’t even want to suggest planning a vacation because I’m going to be the one to end up planning it. I feel like I can’t even ask him to throw the trash out this week without it feeling like I’ve given him an impossible task. And I’m not his mother to baby him either.

Am I being unreasonable??
