I hate sex!!!

I'm about 13 weeks pregnant and I can't stand my S/O touching me, I don't want to be kissed on, I don't want to be cuddled, I don't want to be touched AT ALL, being touched right now I can only explain the feeling as being grossed out! My stomach feels awful and I begin to feel nauseous! I hate hate hate hate hate hate HATE being touched! Don't wanna be kissed or nothing. My morning sickness is through the roof on top of that. I don't like having sex, my sex drive has vanished into a deep abis. I used to have a crazy high sex drive, me and my S/O would have sex at LEAST once a day! Now I hate it! I still have sex with him almost every night but he has obviously noticed I am just not into it, I barely touch him and kinda just roll over till he's done, it makes me feel so awful!!! I feel like a failure of a wife!!! But I just can't help this! The thought of him touching me grosses me out! Its so extreme I've thought maybe I've fallen out of love with him, please don't be rude if you reply, I am struggling so hard with this and absolutely hate myself for it! He's not very understanding of any of this either where this is our first baby. I just don't know what to do any more 😢😢😢
