Good on you for not going in and buying the dreaded booze. Gotta be proud of that.
As for your abusive partner, sounds like you need to tell him flat to change his ways and if he can't, think very hard about whether you want to stay in a toxic relationship.
Easier said than done I know. But you need to put yourself as number 1 priority in these early days, not him.
I hope he is not violent towards you?
