Hey alphabet, welcome back! That's great you decided tha quitting again is for you. If your partner wants to quit as well, good for him too!
I think you know though that your sobriety journey is yours alone. You might have to be the one to set an example, get healthy and happy on your own. He might go with you or he may not. He might down the road join you, he may not. That's his journey.
If we tie our sobriety to others in any way, it puts conditions and undue risks on us.
You can do this, we are cheering you on!
