you are an asshole, you never

loved your wife, you married her for green card and big house. You said that youself, when other poor students are struggling, you can move into big house to live if you marry her. Why are you surprised that your wife has an affair with other man? You never loved her and you used her! your wife made a mistake by cheating on you, you deserve it anyway. If you think your wife is bad, then you are worse!
