Welcome!!!
Sounds like you are carrying a lot, especially if your partner is also drinking. Sadly only they can make the decision to change and seek help but this doesn’t stop you from doing the same.
As you carry this heavy load please look after yourself, it is okay to put yourself first at times.
Go for walks, go out with friends and eat regularly and well.
Seek support from support groups and assistance from services like Mental illness fellowships, GROW, Carers, relationship Australia and beyond blue. These services can also help you with referrals and support for your partner, helping to carry some of that load.
Practise mindfulness which also helps, you can google this, there are loads of resources on the internet.
Take a break, get out of the house and find a hobby or have a cuppa with a friend, someone you are comfortable having a chat with.
And keep up your Communication and conversation with your partner. This is key in having a healthy understanding relationship and working together will help create a strong happier future.
I hope this has helped.
Good luck!!!
