So I got in to one of my top choices, hooray!
My significant other, however, is still waiting to hear from them. Of course this factors into my decision a bit (whether it should or shouldn't is not the question here), but I want to confirm my feeling that asking my POI is completely out of the question, right? Not, "will my girlfriend/boyfriend get in?" but something like, "I am so excited about this offer, but am waiting for a few more pieces of information before making a final decision. It would be helpful to know when the rest of the decisions will be going out, as my partner has also applied to x school and that will have some bearing on my options..."
...the more I think about this, the more I realize there's no way to do that tactfully.
Well, I'll post anyway in case anyone has had experience with this and would like to chime in!
