Disagreeing with a loved one creates a stalemate and puts a solid block in the way of romantic or relationship progress. That's why it's important you consider your reasons for standing your ground. If you're doing so because you don't want to risk appearing foolish by agreeing to something and wish later that you had more facts available, then do some digging or probing. What a loved one wants you on board with benefits both of you. Get the information you need and see how you feel once you have it.
