How to deal with a low sex drive

I have been with my fiance for almost 9 years. We have had some issues and we took a couple of months off a few years ago for him to get his drinking under control. While he was drinking we would go months without any "quality time" because the alcohol affected his libido.

He has got a grip on his drinking but I am lucky if anything happens once or twice a month. It is an improvement but it is still far below what I want of at least once or twice a week. I have talked to him about it numerous times as it is our one big reoccurring fight, but it never seems to get anywhere. We both agree once or twice a week is what we need to be happy but I can't seem to make it happen. He told me once that he just gets so tired during but he refuses to believe that he needs to do anything to fix it.

I am at a loss for what to do and once again I am getting frustrated. I would never cheat on him but I don't know how to make it better. I have tried toys, outfits, talking, but I always initiate and always have to do all the work and it is getting tiring.
