Once you place the acquisition of assets and/or power as the requirement of a happy life, not only will you never be truly happy, you will also never be satisfied. The very few who have happiness with wealth and/or power are usually the ones who were born with it (not to imply that it is a guarantee for many in this realm are also miserable). The ones who achieve it from scratch, never stop to smell the roses.
While you can dress it up in any number of elegant, beautiful or merely deceptive ways, it is simply greed. As soon as you acquire the money or power you desire, it will make you happy for a few seconds before you suddenly realize you want or 'need' more.
Love of another man will not satisfy this need, and that love will be cast aside whether slow thoughtlessness or with sudden great force. The important note is that it will be cast aside.
Having seen and experienced these things, without question, I would choose happy in poverty over misery in great wealth.
So if that's what turns your partner on, you will never really be number one in his life, at best you can become a great trophy if that is your desire.
He may stray from that notion, but if he doesn't within a few months, 6 months at most, then he's never going to change. At least not in a time frame that will allow you a happy life.
