It'san incredibly ignorant trope that people need a romantic partner to be happy. An unhealthy or even a medicore relationship is way worse than being single.

"Happy"
Being single is hugely underrated.

Someone is manipulative or who gaslights, someone who uses their own charisma or fueled by their sense of entitlement.

Sharon Van Etten perhaps?
