Should I be more discreet about personal matters? What do others think?

I've often been very personal in my questions & answers, feeling the freedom of anonymity and distance. But others here are far less so.

I was talking the other day (also back in January and occasionally much further back)
about difficulties in my marriage - seeking to understand.
The feedback was useful and made a positive difference.

It's occurred to me that airing my husband's and my flaws and problems in public could be construed as disloyalty to my husband, especially because I named him.
On the other hand, there are thousands of men with his first name.
It would take a very organised sleuth to piece together every fragment of info to pinpoint exact identity, and I very much doubt that anyone would be sufficiently interested to go to that much trouble.

There's also the potential that others might have similar issues and that open discussion could be mutually or vicariously helpful.

In my local area, I don't feel it's safe to confide in friends. Although our valley contains 80,000 people and the wider region 302,649, the distance between each person is only two degrees. A friend might repeat something in a well-intentioned way and then what's said can travel like lightning and end up dreadfully distorted.
An example, I once told a close friend I wanted to die. The next week, I bumped into an acquaintance who said, "Oh, you're still alive! I'd heard you'd offed yourself."

There is something very comforting about having a place where I can sometimes blow off steam when things get too hard to handle on the inside.
