I envy you your strength. You must be very determined to embrace sobrierty when your partner doesn't.
You have to make your own social life that doesn't involve the pub. Hopefully your husband will share some them with you - cinema, theatre, gym, rambling... I really don't know what interests you. But you have to find an interest and people that share those interests with you. Dancing classes, foreign language, book club, swimming - I don't know. Something, anything, to give you something to look forward to every week.
Or volunteering for AA or AlAnon. You must have a lot to offer other alcoholics.
Hopefully your husband will be fully supportive and join you in some new activities.
