how do I get him in the mood?

Ma
Okay we have been together for about 3 years ... and we haven't done it in like months and I'm getting sick of it... not only that but he won't spend time with me on my days off... we live together but I only see him maybe about 6 hours if lucky.. he won't touch me or anything... I need some help... honestly do I not look good enough for him anymore?
