You are still connected.
Reclaiming the territory of your mind is a conscious step by step power build up.
The moment you start dating new women, you will see them gradually replacing her in your mind.
The vision of her or fantasies about her simply means that she's still your "Point or reference" for the feminine energy.
Realize too that these visions of her won't hurt you.
Even having some romantic fantasies is ok.
You don't have to block all that.
Some of it might even be very pleasant.
Over time though, these visions will naturally fade away and become a distant memory which loses its sharpness.
When this happens, it means that the power she had over you is now dissipated and you are a free man.
You will definitely notice the shift when this happens as you might see someone else replacing her in your mind.
