How do I fake it when I feel nothing?

We got married last year after my parents set us up. They really liked him, said he was stable, respectful, all that. And he is. He’s kind, never raises his voice, brings me tea in the morning without me asking. But I feel... nothing. Not anger, not sadness, just blank. I thought it’d grow, you know? Like maybe love would come after marriage. But it hasn’t. I don’t miss him when he’s gone. His touch doesn’t do anything for me. When he hugs me, I go stiff. I catch myself counting seconds until it’s over. We haven’t had sex in months. He says he’s fine, that he “understands” but I see the hurt in his eyes. I feel so guilty but I can’t force it. I don’t want to hurt him but I also can’t pretend forever. Sometimes I wonder if this is normal. Like, maybe all marriages start like this? Or am I just broken? I can’t tell anyone because everyone says how lucky I am. But inside I’m just… numb. What do I do when the person you’re married to deserves love but you can’t give it?
