See, if I were Cath and got this phone call my response would have been something like, "Gee, person who gave birth to me, it's a good thing you're there since Wren soundly ditched me and our dad for you, you're apparently her only family now. She couldn't even be bothered to show when dad was just in the hospital so I'm not dropping everything because she's there now. Besides it just sounds like her Be A Drunken Moron Every Night lifestyle with her new and real friends has caught up with her. And the last time I showed up when I thought she was in trouble she treated me like dirt. Keep me updated if she isn't fine, but I'm not putting myself in this position again for someone who doesn't care about me."
I'm just not up for a reconciliation where Wren doesn't have to apologize and atone for her heinous behavior, it's bad enough for me that Cath is jumping-to here. And not one with Birth Mom at all.
