I don’t want to feel like this...

As I’m writing this, tears are falling down my cheeks and I don’t understand why. Today I had a good day and it was supposed to be end great. My fiancé and I have not had sex in maybe like 2 weeks and tonight was supposed to be our night. We had been running around all day and when we finally came home it was already 10pm. I went in to take a shower & I asked to come in with me but he didn’t want to which is weird because he always wants to shower with me. Then when I got out, he was playing his video games and I asked him if he was gonna shower & he said yes. He didn’t get in the shower til 1 hour later. By then it was already 2am when he got out the shower. I was already feeling down by now & felt unwanted in some way. He laid down next to me but didn’t mention sex or attempted to initiate anything. Instead he fell asleep. Then I woke him up so he can go to his side of the bed and he asked me what’s wrong cuz he’s seen me kinda down. After I told him I was fine, he asked if I wanted a “quickie”. I said no so he went back to sleep. Now I’m laying here crying because I’ve never felt more unwanted by him before. I know he’s tired but he really hasn’t had the desire to have sex with me. I don’t want to bring it up because I don’t want him to have sex with me because I told him to but because he actually wants to.

Am I doing something wrong? I don’t know what to do and I feel horrible.
