Unsaved husband

I have been saved for over 15 years and it seems as if my husband has gone further in the opposite direction. When I first got saved he did mind me going to church, now it's constant smart comments about the Pastor who just happened to be his 1st cousin or the members. A couple of years ago I noticed that my husband was not interested in sex anymore like he use to be and I also noticed that he was loosing a lot of weight and becoming more distant from me and my children. At first I thought it was another woman and it may have been I don't know for sure. He was and still is staying out late on his days off, but he comes home intoxicated. He is now an alcoholic that has a beer in his hand at all times and he drinks gin on the side.

My problem is that he is not intimate with me until he has build to a point and has to release himself and when he does it's not satisfying and he appears to not care. Another problem that I have is all year long he doesn't take me anywhere he states that he does not like to go out to eat or to a movies, he states that we have different interest. But on New Year's eve because his brother and sister and their wives or husbands go to this New Year's eve ball it's his time to shine as if he had treated me well the entire year. I know that it's me because I feel he should spend time with me during the year if he expects me to spend New Year's eve with him and his family. My other problem is that because of what's going on in our lives, because I feel hurt and lonely most of the time at the New Year's eve ball in order not to be the party pooper I drink to make myself have a good time because I really don't want to be there, I'd rather be in church and the next morning I feel guilty that I have let God down to have a good time with my unsaved husband. Any advice would be helpful, as he has already spend 255.00 for this ball and I said that I was not going this year. There is a lot more going on with us, but one thing I do know is that I love my husband and to much is invested as 27 years of marriage.
