What you were really dealing with was an emotional vampire. These are the type of women who continue to make screwed up decisions and CHOOSE to deal with men who do them wrong. Then they choose an unsuspecting, naive, happy-go-lucky guy to latch onto to drain his energy in order to recuperate their own. They will reel you in with compliments and seduction, and look like the hidden gem to you. Then they will use your time, resources, and ear to tell you how screwed up their life is, how the past guys did them so wrong, and how you are so great for listening and even helping her out in her situation whether it be financially or whatever. Then, out of nowhere, once she is of sound mind and financial position once again, she disappears like a thief in the night, with a host of excuses of how she's so busy or ya'll are moving too fast, etc, and you will find out that she is dealing with one of those kind of dudes that she says are jerks and is screwing up her life. You were the victim of an emotional vampire who will shove all her negative feelings and life situations on you, drain you, and when she is reinvigorated, will go right back into the screwed up situations she was protesting to you about.
One of the surefire signs of this is a woman who constantly complains about how all her past men were jerks and one who keeps on asking you for favors. Don't go for it.
