I just finished reading Codependent No More, after ending a 10 year extremely codependent romantic relationship.

The author said something along the lines of: codependent people who become single often times struggle to ever enter a healthy romantic relationship in the future, because the trauma they experienced from the previous relationship was so painful and all consuming, that they will do anything to avoid that level of pain again.

I can totally relate with this. I fear I will now guard my heart so closely that I will be terrified to ever let somebody in to my life again.

Anybody else relate to this? Or had a similar struggle but eventually overcame it and learned how to have healthy and positive relationships?
