You have fallen for a ‘projection.’ Essentially an idea of who you think she is, not who she is. This is more common among younger people. It can also happen in mature folks, especially those who tend to be more idealistic. Or if life is a little rougher than usual and you are in a more challenging place. It's more likely the case when you are off-center.
Look at your life waryaa. Maybe you are trying to escape from something like self-evaluation. Perhaps there is something that needs to be fixed, or you have a little too much free time on your hands. Put your energy into something more productive.
She is not the only one.
Do not close yourself off to other options merely because of her.
There is a multitude of different prospects. Many of which you could be content with.
It is far better to go for someone who is a flesh and blood individual rather than a phantom or abstraction of an earlier, more nostalgic time in your head.
