Conflict doesn’t mean the end of your remarriage, and can actually make it stronger. There are always going to be disagreements; you cannot avoid them entirely. What you can do, however, is become skilled at recovering from disputes by talking about your perspectives afterwards.
My husband and I grope each other constantly. I don’t think a day goes by without at least one of us copping a feel. I say this proudly because after almost 20 years of being together, we are still hot for each other. And I don’t see any reason to hide this from our kids.
