If I am upset with anyone, it is first myself. I know that Edward what is trying, and he likes to... what is the expression push buttons. He is just as intelligent as you, but he uses it for different purposes. He is also very good at saying just the words to raise my dander, and I should know better.
Please do not feel responsible for his actions. Regardless of how much you two share as a whole entity, he still chooses to behave as he does.
Do you believe he would have found your phone and computer?
