I feel like my husband isn't happy anymore.

he never kissed me, or holds my hand or hugs me, or just tells me he loves me. he never wants to make love, even if I beg, unless he's drinking. he doesn't come to bed when I do, and when he does get in the bed...he doesn't hold me or kiss me or tell me goodnight..doesn't even touch me. I went back to work last week so we really haven't got to see each other, I was hoping he would miss me, but I still can't do anything right, he gets mad at me no matter what I do. he literally can't be happy with me for longer than an hour or two then he gets rude/hateful. I just want to cry..but I've been strong my whole 19 years and will continue to be. I just don't know what to do.
