Tim Matheson says he's no longer getting death threats or money demands from the person who was pissed about his tweet at Melania Trump ... so he's moving on with his life.
We broke the story ... the "Animal House" star filed a report with the LAPD last month claiming he got a series of escalating messages from someone online ending with the threat, "pay me big bucks or I will kill you."
Law enforcement sources tell TMZ ... Tim hasn't had any further communication with the suspect since contacting police, so he doesn't want to pursue charges against the unidentified suspect.
We're told the case is now closed.
As we reported ... Matheson tweeted in January -- shortly after Joe Biden's inauguration -- that it was wonderful to have a First Lady who can speak English.
He apologized days later and admitted his tweet was "stupid, ignorant,& foul," but obviously some of the backlash he got was too much to ignore.
Fortunately ... it seems cooler heads have prevailed.
