Have you considered a paternity test? Do you believe that your ex is unhealthy and she will only mess with you?

I know what you are saying about saving others. For me it is that I don't want anyone else to suffer the way that I suffered so I want to help them. I do, however, let others take care of me and I do take care of myself also. Do you let others take care of you (are you close to healthy people who can take care of you sometimes? or do you distance yourself from healthy people?) Do you take care of yourself? Also, there comes a time when unhealthy people can pull you under right with them. It is okay to help others but not if it pulls you under too.
