How many of you share your friend's secrets with your spouse?

I'm coming to terms with the fact that I might just be a bad person, and I'm hoping to work on this (?possible) character flaw. Does anyone else immediately spill the beans to their partner whenever someone shares a secret and says "don't tell anyone but...." . I just can't help it, I tell my husband pretty much everything and use him as a sounding board to vent but also for unbiased advice. I'm talking about friends who tell me they might want to divorce their partners because they feel alone in their marriage, those experiencing substance abuse issues, those secretly taking Ozempic, and even those who talk poorly about another friend in the group. My husband knows about it all.

I'm trying to understand why I can maintain secrets between friends and family members, but I always have a urge to tell my husband. I wonder if it's because I see him as an extension of myself, or like we're basically a unit? Nonetheless, I don't think this is justifiable and wanted to know if anyone else has this problem?

• Edit: I just wanted to add that my husband is a total introvert, hates social gatherings, grew up an only child, and is a total homebody. He doesn't even have social media. I'm literally the only one he ever opens up to. I'm wholeheartedly confident that he is not sharing what we discuss with anyone else. I also don't discuss our relationship in any detail with my friends/family so it seems as though I only prioritize my husband's privacy and no one else's, which again I don't think is right. However, after doing some thinking, I can say the only line I never cross is sharing gyne/reproductive/women's issues in any detail with my husband - he will never know who has heavy period clots or a yeast infection lol.

• Edit #2: Okay, I get it. Apparently I'm in the 1% of people who do this and the rest of women on reddit take every single secret they've ever been told to the grave.
