"I feel nothing when I kiss you"

Those where his words... My husband and I have been together for 8 years... I would say everything that has been going on lately but I don't have the energy. I don't have friends or family except for him, I feel so lonely... 😢 He says he loves me, but he doesn't feel loved... What do I do? I can tell he is depressed about many things (job, friends, money, life...) But I don't know how to help him, and now that my heart has broken into a billion pieces I have less idea of what to do.
