“My boyfriend is jealous of everyone I talk to”

What could be going on

Jealousy: Fear of losing you to a rival; check whether it's tied to real events or appears regardless.

Abandonment/instability schema: Fits if he expects to be left and reads any attention elsewhere as the start of it.

Mistrust/abuse schema: Could come from past betrayal; check whether he was cheated on or let down before.

Controls a partner's money, friends or movements: Check whether jealousy turns into rules about who you see, where you go or your phone.

Coercive control: If jealousy comes with monitoring, isolation and fear, this pattern of control fits better than insecurity.

Anxious-preoccupied attachment: Fits if he needs constant reassurance and calms down when you check in often.
