If you have a newborn with a man and his other baby mama finds out and starts to harrass you and threatens to beat you up would you file a report on her?

They are not together and haven’t been for 3 years. She knows we are together. She stays in her lane and I stay in mine. They coparent perfectly. We never cross paths and when it’s his turn to have their child it’s a drop and meet outside and go about your day. She just became aware that we’ve just had a baby and now all hell has broken loose. She is now contacting me through fake pages since I’ve blocked her years ago. Threatening to beat me up and now my child won’t be able to be around her child. That she’s gonna tell her child that my baby was an outside baby etc. She and I had bad blood a while back. That’s only because she couldn’t get over that he’s moved on and still inserted herself in his business. Every once in a while she hits him up begging yo be a family and that she’ll take any piece of him he’s willing to give her. Pathetic! Now she’s comparing our children and telling their child that “daddy has a new baby and doesn’t care or love you anymore”. Like who does shit like that? But my question is would you take these threats to the authorities or would you let him handle it?
