My husband won't stop drinking and I need opinions...

Hi ladies. I just need some help on what to do and opinions on what you would do in this situation. My husband and I have been TTC for 3 years with one chemical pregnancy. We have ruled out any problems with me or him. His sperm analysis came back normal and there doesn't seem to be anything wrong with me. I have given up everything to try and become pregnant with a healthy baby. I used to smoke alot of weed and drink quite often on the weekends. I also had a very poor diet. I have completely given up weed and alcohol and have done a complete 180 with my diet, eliminating sugar, processed foods, gluten, very limited dairy and bad carbs. I'll still have a treat meal a week. My husband however, has not stopped doing anything. He smokes weed (not super often maybe twice a week), puffs on a nicotine vape all day long and drinks quite often. Especially during this pandemic, he has been drinking almost every single day. A few months back he ended up in hospital from a night of binging on alcohol and cocaine. He doesn't use hard drugs anymore but the drinking has not stopped. He says he is on board with having a baby and says he wants a family so badly but he won't stop these bad habits. He is a wonderful husband besides the drinking. He tells me he "won't let someone control his life" and won't listen to me when I say that's not what I am trying to do, I just want the drinking to stop so we can have a better chance at conceiving. I feel like I will never get through to him and it's like talking to a brick wall. I will be 31 this year and I want my own biological children more than anything in the world. I would do anything. It seems that he wont. I understand that he has an addiction and I try to be supportive but it is just so so so hard. I am at my wits end and I dont know what to do anymore.

Opinions and suggestions are greatly appreciated. Please try to be kind.
