Those things are easily said when the company is flying high, you are making lots of money for them, and you are seen as indispensable.
I would be very careful with your tactics going forward, unless you are 100% happy to walk. As I have found out through my ongoing 32 year professional career, nobody is indispensable.
Edit - you came on to ask for advice, and then jumped in to threaten your resignation. There are a few wiser heads than mine on this forum. When seeking advice on a sensitive employment topic such as this, I would listen very carefully. Rarely are threats a useful negotiating tool.
