More of the same behavior for me would be to still give her the tickets because of the type of guy I am.
I'm curious what you mean by that, what type of guy do you see yourself as? Because this is what you posted in your OP:
"She filed for divorce because she said I was disrespectful and unappreciative."
If she sees you this way, then giving her the tickets might be a 180 for you. Perhaps you just give them to her and say "I understand our R is over, but I had previously ordered these for you and I still wanted to give them to you just to show how much I appreciate you and the time we had together." If you do something like this, just remember to give with ZERO expectations.
By the way, I assume you mean just give her the tickets without any intent on the two of you going together, correct?
