I'll Die Regretting the Time I Lost

It's been two years since Mel has seen Zacky. Since then, she's became a mom, and Zacky of course is the father but has yet to find out. Neither Syn or Kitty told him the news. When she left Zacky she was heartbroken because of him cheating on her. But the question is, did he really cheat on her? Is that really what happened? Or was it all a misunderstanding? When she goes back to California does she tell him what he's missed out on? Will they get back together? Or will they end up hurting each other all over again?
