Konig thinks that the pact of "no feelings" is mutual. He is unaware he is hurting you so he just keeps doing nothing. At the wedding he was trying to confort you about this being fake and that you wouldn't have to worry. He didn't know you were actually excited and really wanted to be with him, but you didn't tell him. Now, it was too late since he got himself a mistress. You were married to him but you were the other woman.
