My brother-in-law is very close with my wife; should I set some boundaries?

My spouse has a great relationship with their sibling, which is nice, but sometimes I think they are too familiar with each other. They constantly talk about everything, even personal topics. I feel uncomfortable, but I don’t know how to express this situation. Am I thinking wrong? What should I do?

You either have to be clear about this or it will keep going like this. Tell your partner openly, ‘Some special things should stay just between us.’ Establish this as a rule. If they say something like, ‘He’s my brother, how could that be?’ respond with, ‘I feel uncomfortable, even if you don’t understand it, this is my boundary.’

I’m sorry, but there is definitely something going on here. Everything about the conversations seems weird. Why are your private matters going to someone else? It’s completely normal for you to feel disturbed. I think you should look into it; there might be other motivations at play.

Now ask yourself a bit, why can’t you go directly to your spouse and talk openly about this? I think the problem isn’t just the intimacy between you two, but also your lack of communication. If you don’t have the courage to say to your spouse, ‘This boundary is important to me,’ then they have no fault.

I experienced the exact same thing; my brother-in-law was constantly talking to my wife. At first, I thought it was jealousy, but then I realized it was a habit. I clearly sat down with my wife and said, ‘I want to share some things only with you because you are my wife.’ She understood, and they corrected it. I think you should speak openly as well.

Sibling bonds often continue with a dynamic that originates from childhood, which is why they may not respect the boundaries of private life. The main issue here is communicating properly with your partner. If you can explain the answer to the question ‘Why does this bother me?’ from their perspective, they’ll understand better.

Let me add that I’ve told my spouse a couple of times, ‘Let’s not talk about our private matters,’ but they said, ‘We’re siblings; there’s no bad intention.’ I didn’t want to push it further, but my discomfort is increasing. I feel justified in my concerns, so I’m looking for a solution.

Sure, brotherhood and all that is nice, but why is your spouse discussing things with their sibling instead of with you? It feels a bit too much like “Everything is shared.” Of course, you shouldn’t sever the sibling bond, but some things should only be shared with you. Isn’t that what marriage is partly about? :grimacing:
