Could he be gay?

Me and my partner have been together 8 years. We are both in our 40s only he never acts like a hot bloody male. Probably been a problem from the start. Sex seemed to be a chore for him and it always felt mechanical. At first I thought it was me as I was used to a lot more attention. He even told me I was crazy for wanting more. So I dampened down my desires and stopped my longing for intimacy. Sometimes it will be once every few months. He never wants to even act flirty with me or playful. So when ask him why he doesn't want me. He gets angry and says I'm crazy and it's not normal. I feel so hurt and I just want him to want me. My instincts tell me he's a closet gay?
