Relationship advice

Ladies, I really need help with this. So I was with a guy for 3 years almost, and I broke up with him back in March because we were no longer in the same page with things. He wanted to stay in the comfort of his parents home for another year but I wanted to branch out and get on our own again. We had so many communication issues, even when we said we would get better at it. By the only time he really even wanted to spend time with me was during sex and sleeping. We have a little 9month old girl together, and I wanna do what’s right for her. He wants to get back together but I’m not sure if I do. Every time we switch our daughter out, he wants to have sex. He won’t even talk with me about what went wrong in our relationship. I feel like I’m just his sex toy now. I wanna be happy but I don’t know if I could ever find happiness with him again. Sorry for the long post.
