Baby Mamma drama

Don't get it twisted.... I'm not preggers....  but after the discovery of the lying cheating bastard, his wife has apparently gotten my cell and home phone numbers from his phone and has been calling me 5-6 times a day leaving very nasty voice mails.  They're bordering on threatening, and I don't think I can go to the police yet but it's enough to make me think about call blocking or getting my numbers changed anyway.  Getting obscene phone calls at 8 in the morning when I've been out until the better part of 4am is not exactly what I call a pleasant wake up call.
