“My friend puts me down with jokes”

What could be going on

Sarcastic: Fits if the humour carries hostility they won't own.

Passive aggression: Could be anger in disguise; check whether they deny it when you object.

Envy disguised as critique: Check whether jokes target what you're proud of.

Contempt: Fits if you sense they look down on you; check for eye-rolling and dismissal too.

Humour as deflection: A milder cause: banter may be how they handle closeness; check if they stop when asked.
