What did I do...

Its day 3 of the break up and it sucks but I think I am moving along ok. I still cry every now and again but I feel like I'm crying for my daughter because I just don't want her to lose her family. I want her to have both her parents at home together. It hurts me because of its like my fault that things are the way they are. I'm not even clear on what I did wrong to make him want to leave. I have been texting him to ask him what it is I did but he won't answer. He keeps giving me the cold shoulder and I feel I deserve to know what I did that was so horrible that made him want to leave. I'm always home, I never go out unless its with him, all I do is go to work and come home and take care of our daughter. I try to cook and clean when I can. I just don't know how things got so bad. I just wish I had a chance to know what to do different so I could fix this. I want to fix it. I not only lost my boyfriend, I lost my best friend too. He was like my only friend. Now I have no one. I'm all alone except for my daughter. I just hate the way my life is right now. Hopefully, one day things will be okay. I just feel so lost right now. But I know that I just need to leave him alone just seems like he really doesn't want anything to do with me anymore. I just hate that over 2 years of being together is just over like that. I just hold on to faith that things will work out and we will be a family again but until then I guess I'm in this alone. I have never cheated on him so you wouldn't think things would end so badly. I'm just still trying to understand all this. It just sucks.
