My boyfriend says I don’t initiate sex but the reason I don’t is because I dont feel validated. How do I explain this to him?

He says I dont initiate conversations when he knows I am not much of a talkative girl. Its not like i dont utter a word but sometimes i like my space and if we are living together its not like i can entertain him 24 hours. Even when i do, he is busy on his phone or sleeps early, and in turn says that I bore him and he is not on his phone when he is with his friends, which becomes my fault. He says i dont initiate intimacies but as a girl i dont feel validated AT ALL. I have stayed hungry infront of him, cried, listened to his mocking about my body, how i dress and many more things. HOW AM I SUPPOSED TO FEEL EVEN THE MINUTEST URGE TO INITIATE INTIMACY OF ANY KIND? he just doesn't give a shit if i get cranky about stuff, stay quiet on something he said. I myself have let everything go and been normal the next day. And he also acts as if he said nothing wrong, as if everything is normal.
he compares me to randomest of people, doesn't want to hear when he is wrong and bow he is the one who is saying that HE wants to give THE LAST CHANCE to this relationship.
