Coming to terms with being a single mother... Advice welcomed

Long story short, my "SO" and I have been on rocky terms lately. I was forced to move out of my house that I lived in with him (while three months pregnant) moved from Texas to Arkansas to live with my mother because I couldn't afford to live on my own. He's cheated on me in the past and can never give me a straight answer when it comes to serious topics. So I've come to terms with the fact that he will never grow up, never move to be with me and our daughter like he said he would, and never be the husband that I imagined one day being with for the rest of my life. He was emotionally abusive to me and I was so dependent on him, emotionally, for everything. I will admit, I was needy. But now after living apart for a little over a month, I've become stronger. I don't need him like I used to. I'm happy being a family with just me and my baby girl. I feel like I'm a happier person now too.
