If she is working towards the marriage and making baby steps, postpone the deadline. Wait for her and help her through her issues. This woman has a lot of baggage and needs to deal with that first before she can work on the relationship. Losing a child, recovering from a divorce, an affair.....way too much stuff there.
Faith
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
