BEN’S PLAYING MATCHMAKER FOR JEN!

Ben Affleck wants Jennifer Garner to find love again — and he’s secretly playing Cupid! “He wants to see the mother of his children [Violet, 12, Seraphina, 9, and Samuel, 6] happy, and he doesn’t want his kids around some loser,” a source tells In Touch of why Ben’s trying to set up single Jen, 46. “He definitely doesn’t want to fix her up with another actor. He wants someone who’s solid.” Ben, 45, has already “laid the groundwork” with someone he knows from church. “Ben’s keeping his fingers crossed. He hopes they click!”
