Is it normal for me to think he is coming around?

Let me start from the beginning, I met this wonderful guy a few years back when I broke up with an ex. I was going through a really hard time and this guy was there for everything! One night we were talking before we ever got together and he told me that he couldn't be with the person he really wanted to be with and that was his ex (MA), she was also his first love. Well even after he told me that a few months later we started dating and I thought it was over. Well about a year after we got together I got pregnant and we talked about some things, apparently he had not moved on from MA at all. things started going downhill from there, but I truly love him so I told him that if he were to ever get over her then he would have to get back with her because that is the only thing that would prove to him that she wasn’t the same person she was in the beginning of their relationship, I forgot to mention she is in the active army and was not home but 2 weeks out of the year, but anyways I broke up with him and told him to go be with her so he could get over her. Even while we were together I didn’t care if they hung out together as long as he told me. About a month before I had my baby girl him and her got back together and it broke my heart! But I wanted him to do it so I couldn’t fuss; they broke up 3 months after getting back together, like I knew they would. It has been over a year since I broke up with him and almost a year since they broke up and I can’t seem to get him out of my mind! I want my daughter to have the family she deserves, and want the family I have always dreamed of! Let me clarify, before it gets said, that he is a GREAT daddy to our little girl and still a great friend to me as well. a while back he told me that he wanted to give me a real chance one day but just couldn’t yet because he couldn’t guarantee that he wouldn’t leave me for her again at that moment. I commend him for that I really do. Here is my thing; he would always talk to me no matter how bad the situation was, even when he and MA got back together and all kinds of stuff. Now he refuses to talk to me and I cannot figure out why! His sister, who has always been upfront with me, says that he has been thinking of getting back with me lately. This confuses me because he won’t talk to me about anything dealing with us. I am wondering could it be that the reason he doesn’t want to talk right now is that the next time me and him talk he wants it to be a good talk and for us to get back together, and he is just not ready yet? I believe he is over his ex now, especially considering I found out she is engaged now, which makes me think she cheated on him, but that is for another time. I know he has not talked to her since like July of this year. Also I know that he has not been with anyone else at all, physically or emotionally. I stay with him about once a week and we talk at least every few days. I obviously have not been with anyone else because I am in love with him. So could this be a sign that he wants to move forward but in a ways has cold feet about being in another relationship? if anyone could please give me some advice on what might be happening, and please everyone that posts don’t tell me I just need to move on, I have tried oh so hard, and also heard that enough, I am doing this because I want some neutral advice that can kind of look at it from both points of view. Thanks for any help!
