Alcohol addiction, STD

My boyfrie d drinks way less then me and he gets so hammered to the point he falls on his ass and is blacked out and will break something.. Like I have no idea what to do because we share a place. And I like to drink and pace myself. Idk what im asking.. maybe venting? I feel like he have might FASD. And maybe he needs more help? Im activiely trying to get into recovery from alcohol because I recently found out my liver is in cirrhosis from all the junk and alcohol. And it’s so easy for people to say stop drinking. We love each other so much. Weve tried multiple times. Is our love doomed because of this? Im really scared of being alone because I also gave him herpes. Which I know isn’t the worst but I feel obligated to stay with him because of that. It makes me feel so guilty and ashamed. I have told him that I have it and he still decided to be with me. But now that things are rocky and we obviously need help. I just dont know what to do.
