I think my fiancé doesn’t find me attractive anymore😭

We use to have sex all the time. Now we don’t. It’s been almost a month since we’ve had sex during the day and we had sex in the middle of the night(he woke me up) 2 weeks ago and nothing since. He doesn’t touch me like he use to either. What could be wrong?? I’ve asked him to have sex every single day the past 2 weeks and I get nothing. I can’t remember the last time he ate me out but he always expects me to suck him off. I’m so hurt right now. I don’t know what to think.
