Shawn Pyfrom, 22, who plays Desperate Housewives' Andrew Van De Kamp, the troubled son of Marcia Cross's character, won't be coming back full-time, PEOPLE has learned exclusively.
"Shawn's not returning for a full season next fall," a source tells PEOPLE. "But he'll come back and make a few guest star appearances."
The source says it was a tough call for the actor to make. "His decision didn't come easy," the source says, "but he wants to pursue new television and film opportunities."
