Changing in front of each other

ABS19

So my husband and I just went on a trip with his best friend and his wife, we shared a hotel room. The first night his friend’s wife came out of the shower in her towel. I found it weird. This morning while I’m in the bathroom, she changes in the hotel room, hopefully with her bra and panties on (still not comfortable with it). My husband said he didn’t see her... but how the hell not?? It’s a tiny ass hotel room! Anyway, I said I found it odd and felt uncomfortable with her doing that. But now he’s calling me immature, etc. Out of curiosity, would anyone else be okay with this?
