<human>: Can you summarize the given text in a few sentences?

I homewreck a relationship. I've slept with a girl over two weekend ago, I know her for 8 months now. The very next day after we had sex she text her bf confessing and she hates herself now. She cried and basically implied that if she can't fix it then maybe someday we can but she stop abruptedly in mid sentence. I think I have a chance with her. I said I would wait for her, but she stated that she doesn't want me to be a backup.

She just wants to talk to me online only. 

I asked her if she would date me if she can't fix it. She tells me she would never do that. I know I can get her if she's single. 

Her relationship was long distance (almost 2 years now) and she was always lonely cause he doesn't make an effort to visit her. This is only her 2nd relationship too. I advantage of her I feel sick. But I thought I could be the better bf. 

I'm giving her some space so that she can get her bf back. I know I'm in the wrong in this. But if she can't get her bf I would like to date her.

Is the best option is to wait? Is there any other options? I've never done this before until now.
