Here it is. He doesn't believe a damn thing you say. You are nagging. And nagging goes in one ear and out the other. He has heard it all before. And what you are saying is that you are going to let it go until you are finally sick and tired of him and are going to kick him out. Perhaps, it would make sense to say, look buster, you have 6 months (arbitrary) to straighten out or this marriage is over. If in that time, nothing has change, you have to go. You are doing to your H exactly what my ex did to me.
