I would tell him the truth. If you don't take time to enjoy yourselves together, you will likely end up as a divorce statistic. Because that is what happens. You are living the married-singles lifestyle with each of you living separate lives in the same house. It is a recipe for disaster and you know it. You need a night out together sometimes. If he doesn't want to do the dinner and Irish band, maybe there is something he would enjoy more. But doing things together is essential if he wants the marriage to continue.
