Charlize Theron -- Alleged Stalker Won't Be Flowered With Charges

Charlize Theron's alleged stalker can sleep easy on a bed of roses tonight ... the District Attorney has declined to charge him.

We're told the decision on Tuesday to drop charges was made based on a lack of evidence Stanislav Sonseadec intended to place Charlize in any danger.

According to the D.A's rejection docs,Theron's assistant asked Sonseadec several times to leave the property before calling the cops. But law enforcement sources tell TMZ Sonseadec is Russian and there may have been a language barrier that made it hard for him to understand he was unwelcome.

TMZ broke the story ... cops were called to the actresses' house Sunday after a man with flowers for her refused to leave.

She loves me ... she loves me not.
