Reciprocal Pronouns are used when two or more subjects are mutually affected.
I don't talk to my friend and he doesn't talk to me either.
In this case, we use one of the two reciprocal pronouns

We don't talk to each other.
They sat for 2 hours without talking to each other. (one another)
Most children often tease one another. (each another)

Why do couples always blame each other (one another) for everything?

Brothers should back up each other (one another).

Each Other vs One Another
We normally use these two interchangeably but some would argue that when there are more than 2 people involved, "one another" is preferred.
James and Jane love each other. (bidirectional)
James, Jane and John love one another. (Each of these people love the other 2)
However, the followings are also correct.
James and Jane love one another is also correct.
James, Jane and John love each other.
Both can take apostrophe + possessive "'s"
I’m sure they will enjoy each other’s friendship soon.
They sat for hours looking at each other’s (one another’s) eyes.
