If you're going through a rough time with a breakup and can not seem to stop contacting your ex, there is a good chance that this is the same behavior that's responsible for the breakup in the first place. Although you may not want to believe it, there's a good chance that your insecurities triggered the split.
This is a perfect example of someone who has simply run out of options and is allowing their motors to run the show. It's classic insecure behavior.
During the relationship, this insecure supposedly showed up as jealousy and paranoia. In fact, many partners wind up driving their cousin away because they simply can not handle the thought that they might leave or find someone else.
But do not worry; this is something that you can fix. The main thing right now is to remember that, even if your ex does come back, you're going to be the same person and it's just going to start all over again.
What you need to do right now is stop contacting your former partner and start concentrating on improving your own life. If need be, get counseling for your low self-esteem problem. You've been surprised at what a huge difference this can make in your life – not only when it comes to romance, but just about every other aspect.
If you do not feel comfortable seeking help, there are several self-help books that have worked miracles for thousands of others. The more popular ones can be found at all the major bookstores and Internet sites.
The sooner you get help for your low self-esteem problem, the sooner you can start living life again and possibly getting back with your ex. Oh, and do not forget, they are going to notice a huge difference also – and this has to be a good thing.
