I guess "excessive wealth" is very relative, but that's inherent to the concept of wealth. 

 I think how one handles wealth is more important than the amount. If a guy is driving a Lamborghini as his everyday car he’s not on the same page as me. Also if there’s income/ wealth disparity how does your partner make you feel about it? How do they seem to feel about it? I don’t want to be with someone who would hold a grudge against me or treat me as less than because of their material wealth. I’ve seen guys with a little money acting like every woman who says hello is after their bag. Then I’ve seen multimillionaires who were generous with their time and attention. It’s more mindset than pure numbers. 

 It bothers me, even if they try to be nice about it. 

 I get that. My discomfort is more about me personally than someone else’s success. I personally need to confront my discomfort and either change it or accept it.
