I don’t love my fiancé and it’s hard!

My fiancé and I have been together for almost 3 years and we have a daughter together. Well as soon as I got pregnant the intimacy stopped and he quit having sex with me which caused trust issues. I find myself staying for my daughter and falling completely out of love with him because here we are still I have to argue with him for any kind of intimacy and im just tired of it. The thought of leaving is sometimes hard but at the same time my feelings are just nothing. The way he treated me when I was pregnant and making comments about things during sex I just don’t respect him as a person anymore. I just need support it’s just super hard..
