Husband turned me down&slept upstairs

So, we’ve been having issues in our marriage. We haven’t had sex in almost a year, we’ve been going to therapy, (no there’s no one else there was but it wasn’t physical and not anymore), I decided tonight to try and “seduce” him by putting on a blue and black cheetah print teddy and failed. I knew it looked great, the girl at VS couldn’t stop complimenting on it, he even said it looked great but he said he couldnt bring himself to commit to the act because there is this mental block because of everything that is going on between us. Then tells me he’s not really a lingerie guy. So I take it off. I then get spread eagle and even turn around and am on my knees in the perfect shot position and still NOTHING. So I start walking around naked. Nothing. There’s laughing crying then more laughing, so we head up to bed and he tells me “I’d really like to sleep in the spare room I have a lot to think about.” Really ‘you have a lot to think about’ wtf is that? I’m standing there A$$ naked I look great and you want to go upstairs because you have stuff to think about? What am I missing?
