She won’t leave me alone!!!!

He cheated and I knew nothing about it. She sent me a friend request and bragged about how she took my man etc etc. I blocked the page...... she kept making fake fb pages and was still taunting me and I blocked those as well. Then she started using her family’s pages to harrass me. Wtf can I do to make this girl disappear? She even got pregnant and was showing me pictures of her stomach and stuff. I’m so annoyed and disgusted in both parties. I’m no longer with him but she feels the need to still do this. I shouldn’t have to delete my social media to satisfy her at all! I guess she’s doing this so I don’t get the urge to take him back because she knows he wants me back. Not happening!
