Congratulations on your sobriety and finding what works for you.
I am in AA and if I were to feel resentment over someone's sobriety method then I would do inventory on it. A step 4 or a Step 10. ... and I would probably see that I was being selfish and self seeking for thinking that the person should do as I do or as I want them to. I don't know your friend so I don't want to make assumptions about him/her but it doesn't sound to me like they are spiritually well but hey what do I know?! Maybe there is some fear around the resentment too. Anyway whatever it is , that is his/her stuff to deal with. You are doing what is best for YOU to keep YOU sober and that is all that matters! ....
Good luck on the rest of your journey
