My Baby's Father is Confusing Me.

OK so a little background information about me and my Ex/Baby's father situation.
We started dating in high school in 2009 and had our daughter in 2010. I used to live with him and his mom until he recently kicked me out and broke things off with me in FEBRUARY 2012. He used to be so affectionate and caring. Always loved to spend time with me and our daughter until recently. At first after he broke up with me, He said he was sorry and asked if I would consider getting back together. My response was "no" because he wasn't proving to me that he was different. Like a light switch, his attitude with me and wanting to fix things changed. Then it was me who started to call him crying asking to give our family another chance. He then, was the the one saying he changed his mind and that he needed "his time". He is so cold hear ted now. I can assure you that he never used to be that way with me. I was actually the one who lacked affection with him at first.
Im crying all day and i honestly didn't think it was possible to feel this way. I though i had moved on. I guess its because i cant accept the face that its done, but a part of me feels that he would still want to be with me. Im confused because he still shows emotion when it comes to my personal life.
I guess what im trying to ask is, How do I know If he's really done with us?
