One test when in these situations is, "Can we agree to disagree?" If that's a tactic that is successful when there is contention, it shows a pretty high level of trust in a relationship. It says that you both believe you are right, and you're ok just leaving it without agreeing, you still get along in general and still love each other. In places where this doesn't work, I find that it's a matter of confidence. If they cannot agree to disagree, and won't let go until you agree with them, it may point to their lack of confidence in your general thought processes. I.e., if you can't see it their way in this situation, there are likely many situations that you wouldn't see it their way and in aggregate, you'll behave in ways they cannot accept. Depending on the specific topic, maybe that's understandable. Perhaps, for example, you repeatedly make bad investments and they want you to start getting their assent first. But if the matter is not of such significance, there is likely something else going on. It may be that they cannot bear the uncertainty of when and where you'll make choices they'd disagree with and they have a need to get alignment.
