OW is calling my phones

Filled with so much anger but trying to rise above. Don't know what to do with her being in town and calling my phone. She called my house once and then called my cell(with her number blocked). She didn't call back after I answered and told her to quit hating because she couldn't have him and how did it feel to be a piece of meat. Because I know I sent my man into this world unfulfilled because I couldn't get out of my funk. She was nothing but the for the drunken moment. But the want to do serious harm to her is over whelming. specially since she came back to this state and started calling my phones!
