Well Shawn, my first suggestion is to regisiter as Shawn

If you are in a DD type relationship, then its safe to assume you have rules and understandings...expectations. Youre aware of these, so to use a play on words is just an avoidance technique. Congratulations on the victory and all but you had a responsibility to let your wife know that things had changed, and that you werent going to make it by 4. It requires a quick call. The fact that you didnt show up until an hour and a half later shows a distinct lack of responsibility to communicate, especially when she specifically asked for a time frame, to say nothing of its being inconsiderate.
Based on the little that youve explained here, I feel the expectation and responsibility here lies in your hands. If there was a change of plans the thing to do would have been to let her know, one so she wouldnt worry, two so if she had other plans she could adjust accordingly, three if she was planning dinner at a certain time again she could adjust accordingly...there are any number of reasons.
I get that she could reach you, and knew where you were, but that doesnt take the responsibility off your shoulders.
Know that this is only my uninformed opinion, and that there are no judgements here.
Good luck, and if you dont mind Id be curious to know what the outcome was.
