Would the Dursley family be invited to Harry and #Malfoid's wedding? Yes. Malfoid would insist the Dursley family be invited. In fact, she would make it her mission that they be invited and attend. Family is everything. Malfoid would remind the Dursleys of that in her own way. ...and knowing Malfoid, the entire situation would be so delicious. Think about it, she is a Malfoy, and she has been brought up her entire life being proud of her family and where they came from. She has an extremely strong connection to her lineage and still does even after everything that has happened with Voldemort. Harry's connections to his lineage are broken, scattered to the wind, and purposefully disconnected in many ways. He has inherited many things including wealth, but those are just that... things. Petunia and Dudley are his only living blood relatives. No, even if Harry didn't want them there, she would make it happen. She would move heaven and earth to make sure the Dursley family attended their wedding. She would make sure they were treated as guests of honour despite being muggles. The fact that they know about the wizarding world would make it so that she has leverage to allow them in and attend. They would have the best seats in the house as Harry's only living family. She would flatter them by making a speech thanking them for taking care of Harry throughout his childhood, recounting stories she has heard from Harry, but in a very diplomatic yet pointed way. Remember, she is a villainess. Her wit is razor sharp. She would make sure the Dursleys got a standing ovation from everyone as thanks for making sure Harry Potter, the saviour of the world--not just the wizarding world--but the whole world, got to where he was because of them. She would make sure they understood the importance of Harry Potter and what he achieved... and she would kill them with kindness in her aristocratic manner. It would be her exacting revenge on them in a way they cannot escape from. I've also seen the recent memes of Vernon and Lucius being opposite sides of the same coin. I can imagine that happening at the wedding too, the two verbally sparring, but then coming to a twisted understanding of each other. I can see Dudley understanding in a very base instinctual level that Harry is the alpha in this world. He doesn't have much brains, but he understands that much. Harry is top dog in the wizarding world. Petunia would be the one that would have the most difficult time. She hated her sister because her sister was special and she was not. She would end up being surrounded by people who knew her sister and loved her. Malfoid's goal wasn't necessarily to make the Dursleys have a change of heart about Harry. Her goal would be to make them see that he is special and that he is the man who saved the world, the man who saved her from herself, the man who saved THEM. Her pride would not allow her to let them hide away from that fact. She would make the Dursleys see what they didn't want to see and make them accept that's just how it is. And after that... she would invite them to every important event because... family is everything. Voldemort almost destroyed her family completely. Never again would she allow a part of her family to become disconnected for any reason... and the Dursleys were now her family too.
