Husband not very affectionate

Hey ladies I need some advice.. My husband isn't very affectionate towards me we rarely cuddle have sex or anything spontaneous. We have sex maybe once a week or every two weeks. We don't have any kids and were on the same work schedule so we see each other every night when I get off. We're going on 2 years of marriage. When we were dating/engaged it seemed a lot more exciting and touchy feely. Now not so much. We've been fighting his drinking problems for the last year or so and I'm exhausted with that on top of the lack of affection. Ugh what would you do in this situation? Every time I confront him about it he just says "sorry I'll try harder" but never does!! Actions speak louder than words.. Any advice I'm at a loss here
