So I have been married to my wife for about 4 months now, and I just got a call when I was just leaving work, saying that I shouldn't say the word "no" to her, and that I should use different ways of telling her no, like "We shouldn't do this because (blah blah blah). And when I got home, I asked her why am I not allowed to say no, and all she told me was "Because I'll be upset". We argued a bit, and made up about it quickly, but it just left a lingering feeling that just doesn't set right with me.

So... AITA for telling my wife that I should say no? Or is there something else going on here?
