Some people have serious issues in this world. I mean you should be able to date who you want no matter what the baggage is. The "crazy exs" as we call "them" are people who still love the person you are with and will try to cause problems in your life. I know annoying, right? Well, the best thing you can do is stand up for yourself or just ignore he/she because the more attention you let them have, the more your life becomes stressful. I understand it is very hard and frustrated, but don not let them win. Just stay strong because your not alone and it can be frustrated and tough. I am here for you and I will be here for ya. Just comment for help and I will. I know you can win in this battle and stay strong. You are important to people whether you don not see or do.
