I am just asking why do you need to pray the thanksgiving peace of the rosary novena even if the miracle hasn’t happened.
The reason I ask is as you are basically thanking for nothing. For saying no.
People pray for miracles each and every day. And there is nothing wrong in doing so.
However, at times we need to step back and see a broader picture.
In most instances, what we are asking for is our perception of what is best - for example, a cure from cancer. and asking for a cure from cancer is not morally wrong; however, being cured from cancer may not be what God has in mind as best.
Numerous also are the parents, for example, who pray for their children to return to the Church. And numerous are the parents whose children do not return to the Church; or at times, return, but not within the lifetime of the parent.
Perhaps, from what you have said, it might be important to slightly redirect your novena; for a change which you request, and the grace and wisdom to accept if it does not change, and the wisdom and courage to face the trial you have if it does not change.
If you wish, feel free to pm me.
