These messages bother me from my mother in law for some reason

Yes she definitely expect you to mother him. I would tell her that he is a grown up and he can care for his 5 hours sleep

Yes that’s exactly the vibe I got. Take it with a grain of salt 🧂. Shes just a mom worrying about her baby. Now if she takes it further condemning you for not taking care of him or anything like that ; then that def warrants a reaction…. Because you are not his mother ; you are his wife and yes you are meant to take care of each other, but that responsibility doesn’t solely lye on you ; he has a responsibility to take care of himself and his family, same as you.

Why is she asking you if his health has improved!? She can ask him herself! He's a grown man!
When I first read the messages without context, I thought ishe was trying to tell you how to parent your child and I was thinking what audacity she has! Then I saw it was about her own son who is a grown man!
You need to show him and get him to deal with her

I can kind of understand why she’s asking you and not him. He may just tell her he’s fine and to avoid worrying her. My mom and MIL will text the other spouse when one of us are sick and may be resting more, etc.

If that's his reaction then it sounds like you also have a husband problem..

I think to me it just reads as a worried mom who wants his partner to know things she has noticed in the past and that he’s likely decompensated with less sleep in the past. Being a partner and trying to get their spouse to go to bed at an adequate time isn’t that weird to me. Maybe I’m just giving the translation the benefit of the doubt that this was meant with good intention and not that his mom thinks his wife should also be his mom.

I’m Jamaican Chinese so I can’t tell you if it’s Asian or Jamaican thing or both ; but they LOVE THEIR SONS TOO MUCH and it gives them ( their sons) a strong a sense of entitlement. And he won’t see it any other way, other than my mom being a mom. Until you can show him how these messages are off putting ( getting him to view it from your perspective) , you won’t get much of reaction out of him. … if open communication is not working, maybe put him a situation similar and sees how he responds … some people can only learn or understand by experience 🤷🏽‍♀️

I have an asian husband and at least your mother in law messages you lol my mother in law is just like this.. it’s the culture i’m thinking.
