Search Results: not get feelings after sex

I went out with this girl a few months ago. The first three dates were amazing. But then she disappeared. We'd text once in a while but that was it
It wasn't until I wished her a merry Christmas that she started consistently talking to me. We went out the next day, and she said things got dark. After our last date, things got bad at home. She started doing bad drugs and drinking a lot. She got wrapped up with a guy who treated her bad and a bunch of other stuff.
She had gotten sober and moved home the week before we started talking. We had a wonderful time, and she told me it meant so much that I checked on her and I actually care about her. We had sex, and we talked afterwards. She wanted to get her life straight, and I'm something that's stable in her life. I told her I wanted to be with her and to make her happy.
Over the next 5 days, she cancelled 2 dates. Thinking I wasn't going to see her again, I texted her that I wanted to be there for her. I was falling in love with her, and I think she needs someone who treats her like I did. Whether it was with me or not.
She said she wanted to get together to talk. But cancelled again.
She said she was gonna be too busy with work to make our schedules meet. She said I'm a great person, and I'd make someone so happy. But it couldn't be with her. She said she needed to work on herself. She wanted to be single and get her life together. She said maybe we can try again when that time comes.
I apologized for dumping my feelings on her. And said I hope we get another chance. She said she just needs to find who she is.
I don't understand why she didn't tell me sooner. Was she debating letting me go? Was she just trying to avoid it? I'm heartbroken and confused.
