I'm in a pretty similar situation to you. I come from a significantly better-off background than my SO, and sometimes it does get to him. He worries that he will never be able to provide the life I am accustomed to, and truth me told, I suppose I do worry a bit too. Not because I worry about the "things", but simply because I don't want something as ugly as money to ever come between us. I have a lot of beautiful things, but I've unfortunately experienced a lot of ugliness in life.
I don't really have a solution to this problem other than to say make sure you both always remember that your relationship is the most important thing. I know it's a cliche, but money comes and goes; whereas love, if you nourish it, can last a lifetime!
