Falling out of love

Lately I have been feeling like I'm falling out of love with my fiancé. I never thought it would get to this point but I don't want to be pregnant by him and I'm just starting to look at him differently. Don't get me wrong he is a cool funny person but he has I respect for me at all or my feelings. The biggest problem we have is communication coming from him to me and he doesn't listen to me when I tell him something is bothering me. He either says he doesn't care of this is the way it is so if you don't like it you can leave 😒 For example he likes to be very friendly with females or talk to them regardless after I ask him not to because something about it bothers me like it does him if he even thinks a guy might be around or tryna say somethings to me. It kind of feels like he is controlling me and I have no say on what he does and acts. I've been trying to stick it out thinking things will get better but my anxiety has been at an all time high for the past couple weeks since he was supposed to (cheat on me) with some girl that o had to search around for because he wpulsnt tell me about it or her. MIND YOU I WENT THROUGH HIS TEXT AND HE TOLD HIS BEST FRIEND HE WAS GOING TO PICK HER UP😳 but she played him and never got back to him 😡 I just really don't know what to do because I'm like at my all time low.... I live in his parents house with him and I'm pregnant and I don't work since I had to leave my warehouse job due to being pregnant.... I don't have much motivation because I'm depressed all the time from all this on top of being pregnant and can't relieve stress the way I used to.
