What should I do with my relationship?

Me and my girl friend of 3 years separated. She felt a trial of separation will help.We both have issues that caused the break up. I realized my mistakes and that I needed to deal with them. I am doing the things to make the changes like church and counseling for me. She found faith 10 months before I did, She feels that I was not emotionly supportive. I worked all the time and bottled up my emotions from my past. She did not work at all. I gave her the space and time to think.. She calls and gets mad, cause I am stepping up dealing with my issues. She say now you being a man since I am not there. Also throw it in my face about me not being emotionaly supportive and awful things like that. She did things that made me feel a certian way, but I am not trowing things like that in her face.but I am trying to be supportive of her. I love her dearly and want to work things out. We need to work on each other in order to make this work first. Since I am going to church I realized a lot. Now for her things are going as planned for her. She has a job, but no home for her 3 boys from a prior marriage. She allso wants me to help her so she can get a place, but since we split I am trying to make ends meet so that I can have a roof over my kids. I have two boy myself from my prior marrige. I offered for her to come home and she refuse. There is no abuse if you thinking that. She rather give her kids up to their real dad and her live on the street. I feel that she loves me at times when we talk. She feels that if I keep on the track that I am going then yes we will reconcil, but she needs to work on her self. She admits being a bad step mom to my kids and wants to work on that. But now since things are not working out she is being so negitve and hate ful. I don't even know what to do anymore. I have hope and faith that this will work out and have this gut felling it's going to work out. I told her we need not to argue, cause it will get us no where. She agrees and then she say mabe that is what we need, cause we really never argued. I don't want to make things worst or regeting what we say out of anger. She has already said some awful things. I have never seen her angry like this before. So what should I do? Should I continue to have patience or should I let her go?
