What's the opposite of Ben Affleck and Jennifer Garner divorcing?

How about calling off the breakup and getting back together to welcome a fourth child? Crazy, right? And yet: “Friends are expecting an announcement very soon that Jen is pregnant,” a source tells Radar Online.  “Jen has played Ben like a fiddle. She was determined to make him ‘walk the plank’ over his wild ways. She believed he would come to his senses and they could save their marriage. She’s always wanted another child with him. Even since they split, she’s gushed publicly about how he is the love of her life.”

Man, some people just don't know how to break up.
