Can i request Schengen Visa to be cancelled?

[CK Gbor]

After 2 years chatting online, i kinda like this girl. I visited her country and we got engaged. Then comes my duties to bring her closed to me in Europe. After our engagement, her attitude really change and she turn off completely her emotions. Most of my people believed she is a scam but i reject the idea until she have her Visa ready in her passport then she knocked me off.
Is there a way to request from the immigration services or Police to Cancel this Schengen Visa or stop her at the port of Entry to the Schengen area??? i am the host and the full sponsor behind this application.

The Schengen state involve in this matter is Sweden.
