If you are going crazy wondering, "why does my ex ignore me?", you aren't the first to be hung up on this problem and you won't be the last. Do you wonder if there is anything you can do to get him to start paying attention to you again? Have you friends told you to just move on but you just can't make yourself do it? It isn't easy trying to get an ex to pay attention to you again. However, there are some things that you definitely shouldn't do unless you want to make sure he stays away for good.
