When do I get scared?

When my wide says "hmmm okay do whatever you feel is right!"

I am fine if she says "no you will not" or she says "I think it would be good if you don't do that", but sentences like "hmmm okay do whatever you feel is right" make me very tensed.
Last week I wanted to play a game of hockey and also umpire a match, I knew that would take around 7 to 8 hours of my day, I asked my wife "if she has some other plans in the afternoon? If she didn't have any plans then I wanted to umpire because there weren't many who were ready to go away to St Ives and umpire, so I would have to go."
Her answer was "do whatever you think is right!" I went mental & still went.

Rest you all might understand what was the music when I reached home at 5 PM.

Here is a list of things "what she actually means" when she says:

1. Hmmm do you really want to do that? It actually means "no don't do that"
2. Hmmm if you think so what can I say? It actually means "Do as I say, don't use your brain"
3. Ok so you think this is correct? It actually means "you are wrong"
4. Do whatever you find is right. It actually means "you must not do that, because i don't like it"
5. Hmmm hmmmm hmmm that is fine. It actually means "that is not fine" (the three hmmmms mean NO NO NO)
6. Just think about what you have done. It actually means "you have pissed me off and you are a dead meat now"
7. I am not hungry. It actually means "she's just recalled what you had done 6 months back and although you have apologised for that, there is still scope for few more apologies"
8. She gives you single syllable answers. It actually means "she's just recalled what you had done 6 months back and although you have apologised for that, there is still scope for few more apologies.
