Very new, help need with 21 and 55 unchanging

Good Afternoon

I am extremely new to this and am really struggling to link the hexagrams.

We have been split up nearly 3 months now, but I don't believe its the end, for various reasons. We are not communicating at all now, for last week or so, as I told him how I felt and he struggles to deal with his own emotions, never mind anyone elses. Very complicated man!

I asked 'if I am to have a future relationship with David, how should I proceed?

I cast 21 unchanging ?biting through??????

I then asked ' what do i need to bite through and how?

I cast 55 unchanging? abundance????

I am at a loss as to what if anything it is I am supposed to do and don't want to ask anymore questions until I understand this.

Many Thanks for taking the time to read this and more thanks if you can help me
