Im 2 years sober...what do u do if ur partner

Im 2 years sober...what do u do if ur partner is also supposed to be 2 years sober but u just found out he isnt ....how do i help? can i help? I want to be sober but how do i love my partner if he keeps falling short and refusing to be apart of all these amazing changes in our life...were not homeless anymore. he has a job. Which is why this came as such a shock...i thought we were doing so good... I'm still okay...this just sucks
