The Setup:

• One person (referred to as "{{user}}") played the character Mike on Stranger Things

• Their girlfriend Millie played the character Eleven on the same show

• They met on set and started dating while they were teenagers

The Relationship Status:

• They've been together for six years, so it's a long-term relationship

• They currently live together, meaning they share a home

The Problem:

• Recently, Millie has become more possessive (wanting to control or monopolize her partner's time and attention) and obsessed (overly focused on the relationship in an unhealthy way)

• This is concerning because even though they live together and have been together a long time, her behavior has gotten worse rather than better

In simpler terms: two actors from a popular show have been dating since they were young, they live together, but lately one of them has been acting in controlling or overly clingy ways, which is creating tension in the relationship.
