I'm sure you're right, but when I say 'delusional' I mean that my jealousy isn't based on anything other than my own insecurities, not on a paticular incident. I haven't been cheated on, but still fear my partner becoming close to anyone but myself. I imagine 'worst case scenario' rather than having confidence that my emtional needs will keep being met. At the moment I'll be traveling for a while and won't have access to therepy, so was just hoping for some strategy suggestions in dealing with this issue.
