I'm more open with many men than my wife, who famously laughed reminiscing on one of her exes who opened up to her and cried.

I've yet to see the clam closing up than I did on the day. Sadly it happened way too late for some things.

So yeah, don't be vulnerable around women. That's the warning my wife gave me.

In some topics yes (not just any man, male close friends), but not in some others.

All in all, I am most open to her from whole mankind, but thats also due to the fact she is not same as typical women are in these aspects. It took me some time (and painful breakups with other women) to realize who I am, what and whom I want next to me and then find her.

Still, some topics are simply not built for women, and thats fine, some are not built for men.

Is it really so hard to understand this?

I am very different around my wife than random women.

We aren't talking about spouses.
