I’m not sure why everyone conflates agreement with support. I would say your husband is supporting you. To simply blindly agree whilst privately disagreeing isn’t support, it’s low level sycophancy. I’m sure if your employers came round he’s not going to throw you under the bus, but telling you his concerns is supportive and should be viewed as such. You married a partner, you didn’t employ a henchman. Don’t mistake agreement for support because they aren’t the same, you sound like a good team and that’s how it should be, if you want unconditional support, get yourself a Spaniel or Golden Retriever.
