Please I Need Help On This One, Before Its Too Late.?

It all started when two girls wanted to experience being with a girl. I met this girl last year from a dating site and she also wanted to experience it. She told me she has boyfriend and just wanted to see how it is. When we met she was so nervous she couldn’t look me in the eye. After a couple of weeks, we experience our first kiss. In which, it was great. It felt weird at first but at the same time it was a wonderful experience and I liked it. One month passes by and we rent a hotel and experience our first time being with a girl. We both were nervous and didn’t know what to do. Somehow we did it. Let me tell you it was weird but great at the same time. We both got what we wanted. But after experiencing our first sex encounter. We wanted more so we started to see more of each other. Within time we started to feel some kind of feeling for each other, even though she has a bf. I told her how I actually feel about her and I express my feeling to her, and then she did too. I told her we couldn’t see each other because I didn’t want my feeling to get deeper, due to the fact that she has a bf.
She said no that she still wanted to see me and that her relationship with her bf was already messed up. They already been having problem. So I stay and continue to see her more and more. So I ended up falling in love with this girl, and supposely she did too. When had a relationship going as a couple even though she was living with her bf. As time passes by she was getting jealous when I spend time when a guy that I used to dated. I told her not to worry we are only friends and nothing more then that. But she knew the guy like me a lot. So I told her, you have a bf and I’m sure you go out with him. She said that it different because when she goes out with him they don’t kiss or hugs. I told her it doesn’t matter you did go out with him.
As time continue to pass by, by February of this year our relationship was getting worse.We started to agrue a lot, and we hardly saw much of each other. I broke up with her a couple of times, but we always got back together. I forgive her and she forgav me for my mistakes. There was time when she spend most of the time with friends and not me. I also expressed my feeling to her but she always took it as if I was complaining to her. As time passing by we argue more and more and less time. She was very outspoken and rude when we argued most of the time, and that got to me a lot. She disrespected me most of the time and she was very inpatient and wanted her ways. I’m very simple and wasn’t as delicated as she was. She lived like 40 minutes away and I drove most of the time, due to she would complain that its too far. If I wanted to do something with her and she didn’t like where we were going. She were complain and end up not going and we ended up doing what she wanted. I said something to her. She complain. I’m the type of person that doesn’t like to argue a lot. So instead of listening to her argue if we didn’t agree on something. I would let her get her way. She always though of me negative, for example just recently she applied for a job and her interview went well and she got the job. But the company she applied too had to send the paper to coorparate, in which they did. She got a call yesterday saying that she didn’t get the job after all due to her D.U.I. She was disappointed and she thought I wanted her not to get the job. I told her she was wrong, I was happy that she actually got the job. she makes it seem that I’m a bad person when all I did was supporting her and being there for her.
Well just two days ago I broke up with her for the last time and I told her that its final. I couldn’t take it anymore. Despite all that, I’m in love with her and I miss her like crazy. I don’t know what to do now, I know it a very difficult situation to deal with. I don’t know if I should call her or just wait and give her sometime. I want her back but I said it final.
Please any advice I would appreciated.
