In Surrendered Wife, Laura says never tell your man 'I told you so!' when you were right about something. But what's the appropriate alternative, in the cases that you were right?

Recently my bf and I had several casual disagreements wherein he insists that A is true, but if I am well studied in that area I happen to know that B is true. I study something that comes up a lot in daily conversations, but people who don't study it have plenty of misconceptions about.

When trying to prove his point he will use logic and also credentials such as experience or observations etc, but the only times I insist on what I say is if I studied it in university already.

Anything pertaining to my field of study, I turn out to be right over him, even if his credentials or logic seem very strong in the moment. If I'm not certain about something then I won't insist it. Instead, I will admit "I'm not sure" and let it at that.

In such disagreements I stay calm so long as I know that I'm right. If I try to explain why I'm right, he won't always listen if he thinks he's right because his logic is stellar. If he starts to get worked up I just save my breath because I know I'm right. But if he asks me to explain why I think I'm right over him, I begin, but I might also get worked up when I feel he's not convinced.

Then he will go and verify it - say, a quick Google search. When I turn out to be right, he gives a laugh of relief, hugs me tightly then says "You were right! Oh, you're always right. I should have just listened to you." Then he begins to list other instances in which I insisted something and turned out to be right. As I said, I don't insist something unless I am certain that I am right. But his credentials are believable, too, like strong evidence or culturally-accepted hypotheses (we're from different cultures), so I don't dismiss his ideas either, instead I try to pivot them to my own.

My ex told me that he felt insecure to talk with me about this topic because I know lot about it. But this topic is unavoidable in daily conversations especially between lovers/family. Then my ex went off and tried to study things which might be useful in daily conversations, too, but his interests remained niche and he "felt like a failure" (his words).

I know that if my boyfriend thinks of me as 'always right' over him he might feel emasculated. What should I do?
