My ex BPDgf and i used to text each other often. However on a few occasions i would get a reply to one of my texts to her saying, " This is Jim ( not real name) I am using Jeans ( not real name) phone today as my own phone has not been recharged" Jim was my exBPDgf's ex husband. He visited my exBPDgf home to see the children on occasions.
I knew how the text had been worded that it was not Jim, at all, but Jean who was pretending to be her ex husband Jim.
Was this a form of
Triangulation? If so, what was the purpose of doing this?
