Emma Stone and Andrew Garfield can't live with each other — but they can't live without each other either!
"Andrew just can't let her go," an insider told RadarOnline.com. "It's like he only wants her when he can't have her and it's really messing her up."
As Radar reported, Stone, 27, and 32-year-old Garfield recently split after dating for nearly four years, but the two had a hard time saying goodbye for good.
"They fought over her partying ways and his wish to move to New York, but their constant back and forth and pining for each other is driving a lot of their friends away," said the insider.
"It's an unhealthy relationship and he's doing all he can to win her back — again," continued the source, who noted "a reconciliation appears to still be possible."
"She's softening against his charm onslaught because she'd rather be with him and unhappy than alone," said the source. "It's a strange co-dependent relationship and there's a growing number of friends who are desperately trying to talk them out of yet another doomed reunion."
Long story short, the source added, "They're just not a good match."
