text: The problem I have here, is he didn't even admit that he did wrong. To say that he didn't know what he was doing is a lie. He betratyed you and the relationship that you built together. Whether drunk or high, he still knew what he was doing by being with someone else besides you. An affair means it was more than a one night stand right?  \nI am assuming that you are not married. You need to decide whether or not you want to remain in the relationship, if he seems to be willing to reprove himself to you, and if counseling would not be a good option so that the both of you can heal. \nI am sorry that he hurt you. That is the worst betrayal there is.
