My success has alienated me from my friend group and I don't know what to do

To put it frankly, I've been making a lot of money recently and I feel distanced from my core group of friends, who are all great people that I share many genuinely fond memories with. Most of them are humanities and art grads from my old school so I've known them for 6+ years but I've feel as though I'm being stigmatized for having a great job (only a few years out of school, mid six-figures) in the sense that I am called "the millionaire" and there are a lot of references, snide and otherwise, to my income. It's just strange because we've been friends for so long. I love these people and I don't know what to do.
