B,

It's very hard when someone is evasive and vague about their intentions. I can see how this would be frustrating and stressful for you. Also, when a clear boundary has been set up and we're the last person to know?

I would agree that your uncle should have been more forthcoming. I also see why you're confused and bothered by it.

I agree with Echoes to write a letter stating what your needs are directly, but also to keep in mind that this may not be the person to give you what you need. Do you have a backup plan, are there other resources you can draw on?
We will certainly support you here during changes in your life; I know change is very hard for us...

I also suggest to practice some relaxation, self-soothing to keep you grounded during this time...If I relax enough and let faith in , things usually work out. (This sounds idealistic I know, but it really works...acceptance is so hard, but so important for us).
Sending positive thoughts your way B. Let us know how it goes and how you're making out.
