How to reply when she texts "k"
Verdict first
A lone "k" is a full stop. Don't send a paragraph after it. Either leave it, or change the energy with one light line — and if she's annoyed, ask once, directly.

Read the context
After a logistics message ("I'll be there at 7"), "k" just means okay. Nothing to fix.
After a long message from you or a joke that didn't land, it's a sign she's not invested in this thread right now. After a disagreement, it's annoyance.
What to send
Use the last one only if something actually happened. Ask once, then drop it.
What not to send
"Is everything okay??", a wall of text, or matching her with "k" back. All three keep the cold going.
Verdict
Short answer, short reply. Never chase a "k" with a paragraph.
