Is it time to go or do i just need to have a serious talk

So me and the man have been together for over 2 years now we arent together right by my choice but sone times we are intimate he knows I do want to have kids but not until were married and out of my parents house. I go to sleep around him a lot because i barelu get sleep with my school and work schedule And i make him where a condoms but lately hes been waking up to with sex and hes not wearing a condom. Which he knows i dont play about. And then he keeps saying im going to give me his baby. Im pretty sure he nuttin in me a little but not all the way. He use to respect my beleifs but now its like he doesnt care. He the only one i ever been with.
