It seems that everything is clear and obvious here:

Do not be rude, do not offend, do not offend - then everything is okay.

BUT!

I have discovered many more "non-obvious" signs of toxic communication and relationships.

These are the subtle ones:

"... why do you need this?"
"... I wouldn't pay that much for jeans / jacket / bag / shoes!" (which you already bought, of course).
"... why didn't you say that you will go / go / make / buy?" etc.
"... I don't understand how you can work / spend / sit online so much.


These are far from all examples, but even in them one can already read depreciation, comparison and a desire to control.

If in communication you at least sometimes have to explain / make excuses / apologize for your choice (which did not harm the other) - this is toxic.

And sometimes these are purely "little things" that leave a disgusting aftertaste.

There is a verification question: "Is it difficult for me to be around this person?" If you are uncomfortable, if you constantly have to make excuses, if you no longer have free space from "labels", and communication is based on the principle of "one-way" (you give, he / she accepts), then such a relationship can be considered toxic.

Sound familiar? What do you do in such cases?
