My W decided she was going to "try" a couple of times...and that was the word she used...she wasn't serious. She was confused and knew she shouldn't throw away the M but was still involved in EA and not committed. The "trying" didn't last long. This time she is committed and her actions show that along with the words this time.
I think there is distinction between "trying to try" and "being committed to try".
You can say "I will try to work on the R", but there has to be a commitment to do so.
