I Give Advise But I Need It Badly

Here is my problem: I been with my girlfriend going on 6 years on and off. When I say on and off thats because of my foolishness. Now my girl is telling my that she want space, and the reason why she want this space is because of her co workers telling her about their problem and she relating it to our problem (that I thought we was working on together). So when she told me this I asked for advisor and you guys told me to give it to her. But me being hard headed, I told myself that I was going to let that happen and all thats doing is hurting my relationship with her. The other week we went out to eat and we set up a date to go on the next week but when that day came I called her phone 7 times and no answer and when she answer the phone she told me that she was get her hair and nails done. I asked her what she was doing later she told me she don’t know, then I reminded her about the date and she told me she didn’t think we was going out. after talking to her on the phone for 4 min’s she called me back and going to ask me why I’ am asking her all these question and bring up old stuff like when I was out doing my foolishness she was not asking me any question. and at the minute I was at my friend house with his family around me so I could not go into the conversation like I wanted, so what I did was just listen. and while I was listen she was crying and talking about her she asked for space and what im doing (e.x living together, going on dates and asking question) is not what space means. So I told her that I cant speak at the moment but when I get home we can talk about it, she tells me that she don’t know if shes going home. By the time I got home she was not home so I called her phone and it with straight to the answer machine and then I tried again and it rung out and thats what it did for 6 more try. When I woke up the next morning she was coming through the door, I didn’t say a word to her and she didn’t either, I went back to sleep and when I woke up I asked her where she was at and she said that she was at her friend house and that was the end of our conversation for the day… So my question for you is what should I do as a man who’s in love with this person that he done some selfish things to.
