You two need to seek counseling whether it's a marriage counselor or your clergy person (better a marriage counselor but the clergy person probably won't cost money). You need to address whatever the problems in the marriage are, so you can fix them. What changed for him to cause his behavior to change? What's changed for you?
His behavior changes and it hurts you. Because you are hurt, you stop taking good care of yourself. Alas, that isn't likely to bring him back around. The less appealing things are at home, the more likely he is to continue to focus his attention and energy elsewhere. You have less sex, you're unhappy so don't enjoy it as much, you're not taking care of yourself, thus sex becomes less desirable for you both, and the situation just gets worse and worse.
Good luck to you. Talk about it with an unbiased 3rd party. Get some help with problem resolution skills, communication skills, and coping skills. The first year or two of the marriage is the hardest. You're both making a lot of big changes in your lives.
