You're right- my ex likes the truck, but she never drives the truck and won't ever drive it. The kids need the truck. That's the part that makes me so upset and I think where my emotions come into this equation.
Yes, I found that any logical discussion with BPD mother about something she had let to an escalation. There's no way to know what emotional thinking is going on or what her reasons are.
For me, I had to consider everything she owned as off limits. Not for discussion at all.
I think a lot of this was about her feeling in control. We knew to not touch or go into any of her things. When we helped her move to assisted living, I wanted to salvage any sentimental items out of her house that could not go with her in the move. I even felt fearful doing this as before she'd have escalated if we even tried. I found things like family photos that I had never seen before. Even if she wanted to keep then, we would have appreciated seeing them.
The sad aspect of this is that- these are the things that build connections. It's not only about the possession. Gifting or selling the truck to your D- who is clearly not spoiled and responsible- would have been a positive connection. Gifting the inexpensive item to her grandchild could have been a positive interaction for my BPD mother too. But instead for her, these situations somehow felt like threats, someone taking something away from her- and while the possession might change hands, the emotional connection for all would be a gain.
Your ex (and my mother) can either build a relationship with her D or not, and perhaps this is the best she can do.
