Good idea for next time: Choose someone who doesn't leave

 I sacrificed a lot for her; my time, my sanity, my health, my financial wellbeing. . . And now where is she?  I look around me and no one's there.

And when the girl leaves, you always dream about her. You always think, "What could I have done differently? Could I have saved the situation? Was it my fault? Am I the loser here?

Well the bottom line is, she wasn't the person I thought she was. She was hell to stay with and hell to leave. . .

And now I can choose whoever I want, although, I think I should probably choose someone in line with my beliefs: For one thing, don't just leave when the other person is experiencing problems in life. Don't kick a dog when they're down. She did.
