Home again, after a night at work spent dissecting this from one side to the other and up and down (my job only requires about 5% of my brain power, so it wanders).
I believe one of the following to be true, but am not sure which:
1. She has forgotten my BPD diagnosis.
2. She's not as familiar with BPD as she should be.
3. She doesn't care how this affects me.
4. She's right to give the time to someone else. I am a difficult client. I know that. I'm needy, stubborn, I hold on to slights from 50 years ago, can't let anything current go, either, cross boundaries with regularity. I don't want to spend time with me, either.

In case you can't tell, I'm leaning towards #4.

(I wouldn't dare say that quote to her. If one is a good little boy, perfect in everything they do and say, people won't leave you. Which, of course, is factually incorrect, but is emotionally the core of my being.)

So, so much for that.

Thank you all for your considerate replies I appreciate you having taken the time to share with me.
