Do you resent him because being sober seems to be easy for him and hard for you? Or because now you feel pressured to stop drinking? Both?
You know his sobriety is his and yours is yours, right? And maybe it's not as easy for him as it seems? When I decided to quit I rarely talked to my husband's about it because he still drinks and it made him defensive about it. And I knew I could easily let him being defensive be an excuse for me to give up and start again. So I mostly dealt with the tough times on my own.
If you decide to quit drinking, it needs to be your decision to do for you and your life, nothing and nobody else. His drinking or not is immaterial.
The decision is yours.
