<human>: Summarize the given text in a few sentences.

My wife and I have been married for 9 years, together for 12 total. Our relationship overall seems pretty good - we don't argue much, we have a comfortable life, etc.

Recently though, she's been telling me that she doesn't "feel close" to me and that she need me to "be more vulnerable" and open with her.

I'm a very rational guy, and emotionally closed. I don't like to share my feelings, and I don't feel better when I do. 

However, I do like to hear people's opinions, and find them helpful in figuring things out, so here I am.

I've tried to be more open - sharing things that I consider to be "vulnerable" like my fears of failure on certain things, regret at decisions I've made, etc. But these don't seem to be what she's looking for. In fact, she will often be dismissive of such disclosures or even mock them. Which of course wants me to share even more with her - Not.

She's not quite able to express what she means, she just says she'll let me know if I get it right. ?!?!

So here I am, wondering if good citizens of the internet have some ideas. 

In your responses, it would be helpful if you would let me know if your comments are

1) Actual personal experience with this situation in your own life

2) Second hand experience with this situation with someone you know

or

3) Pure opinion/conjecture, not based on actual experience
<bot>: My wife wants me to be more vulnerable, and I don't know what she means. What does she mean, and why?
