What should I do? What should I say?

Ex/baby daddy let me and our daughter come back to live with him after kicking us out because I had nowhere to go. It's been a neutral relationship. Just coparenting. All of sudden last night, he loved up on me, and we had seggs. But today, he's been treating me badly, making me feel worthless again. He's been talking to another woman before he kicked me out and still is. I still love him. But he's told me he hated me and no longer loved me. I've been trying to let go. But I feel like I fucked up. I want to cry, but crying does nothing for you. Any advice on what to do?
