Love life?

Hey,

does anyone know how to make their ADHD interested in sex? I feel like having good sex together used to be a project that my husband worked on and then once he finished figuring it out he just...moved on to another interest? I have tried talking to him about this, tried coming on to him, tried wearing sexy/no clothes, tried priming him earlier in the evening that I was in the mood, I have even tried making sex appointments with him. So completely spontaneous through completely planned and just...nothing. He's tired. He's preoccupied with work. Or he is so awkward and weird about it I just don't want to any more because I feel like a sex charity case. It's not a functionality problem, he just doesn't want to. He even said to me he feels satisfied that he could probably go the rest of his life without sex and not care. I'm almost 50, nowhere near being ready for this. I'm so sad and confused. Sometimes he comes onto me, calling me sexy for example, but it's like he just checked off a box he thinks will make me happy and doesn't go any further. Like: compliment wife, check. I don't want a platonic best friend, I want a husband.
