Well, Harry is just as much to blame for everything, perhaps, even more to blame. He rushed into the relationship and into the marriage when he should have stopped and taken more time. If Meghan threatened to leave the relationship, then a thinking person would wonder why the rush?
Harry's not smart, he's immature, and does everything in a rash manner. All of his words and actions have dug his grave and now he has to lie in it. We all know it.
