Hex 2 Unchanging - dealing with a boundary

Hi all,
I have been lurking for about six months now and have been doing readings and using the search method to find similar threads to readings I've received. They've been very helpful.

I'm asking for insight into a reading about how to deal with a frustrating friend who is very hot and cold, offers her help but then ignores or flakes out later.

I'm at a point in my life where I don't want this kind of dynamic. My two choices it seems are to say nothing about the behavior, or to express that it makes me feel devalued as a friend when she offers to do things and doesn't come through without a word. The question I asked the Yi was, "Give me insight into the correct words to use to express myself so that I've stood up for myself."

I got hex two unchanging (for the third time this week actually). The back story is that this is someone whom I've let push me around like this in the past. I'd like the cleanest resolution so that I'm not wasting no energy.

My interpretation of the hex is to literally do and say nothing. This seems like a doormat decision, and I'm not sure what else to make of it. Any insight?
