Hello HisMom

,
Unfortunately isolation is one of the favorite tactics of BPD mothers. I was raised by a BPD mother myself and have experienced this firsthand. Like not being able to use the telephone without her interfering, not being allowed to leave the house etc. Your grandson is still very young but in my experience BPD mothers isolate their children for two main reasons:
1. To make it easier to control them
2. And/or because BPD moms want all the attention focused on themselves
As an outsider looking in it is very difficult to understand why BPD mothers are often so controlling and jealous of other people getting attention. Perhaps this controlling behavior gives them a sense of stability because they feel like they can’t control any other aspects of their life but now at least they can control their children. Having all attention focused on them may give them a sense of self-worth and seeing other people get attention is something they might find threatening. Another very troubling explanation for their controlling behavior can sometimes be that they have sadistic traits and actually ‘enjoy’ hurting their children. You say that your grandson loves being around other kids and being part of the action, maybe his mom senses that and enjoys taking away this thing that he loves. Do you feel like any of these explanations might be valid for your grandson’s mother?
