Questions & Answers about После разговора с другом я почувствовал облегчение.
The preposition после (after) always takes the genitive case.
- разговор is the nominative (dictionary form).
- In the genitive singular, it becomes разговора.

The preposition с (with) normally takes the instrumental case when it means with (someone).
- друг is nominative.
- Instrumental singular of друг is другом, but here we have с другом.
The ending -ом is reduced in pronunciation, but in spelling it’s другом. In the sentence, due to context styling, it appears as другом; if you saw другом, that is instrumental.
So:
- с кем? → с другом – with (a/my) friend
- other examples:
- с мамой – with (my) mom
- с братом – with (my) brother
