If Jon wants to work of piecing, then he acted wrong. If he is ready to walk away and move on, he did nothing wrong.
They both acted incorrectly, the W said some terrible things to Jon and it would be hard to remain calm and stay with the DBing.
The comments about the W being out of line and not respecting him etc are correct, but how many times do we describe the WAS as being of clear mind? We are to assume they have been abducted by aliens and we are not to believe what they say and half of what they do. It is unfair to expect the W to act or think rationally so soon into piecing attempts.
What I hear is the W saying she wants to feel important and valued (don't know the history of the M but I assume she probably has insecurities).
I think Jon did no wrong bringing up the trip, but should have taken her response and started to dream or plan on the future. Validate her feelings and work on what could be done in the future to work on them as a couple. Jon did this, but after tempers had flared.
With so much promise and hope built up during the week I cannot help to think they both were caught off guard when relaxed on the date and those old feelings came back up.
Jon, if you want it, dust yourself off get back up and work forward with solutions.
