How do I know if my relationship is unhealthy?

Sure, nobody’s relationship is perfect, and people make mistakes. But if you feel like you’re being treated badly, you probably are. Listen to your gut. Healthy relationships make you feel good about yourself — unhealthy relationships don’t.
Lying, cheating, jealousy, and disrespect are signs of an unhealthy relationship. So is trying to control a partner. That includes:
keeping track of where they are and who they hang out with

preventing them from having money

checking their phone or e-mail without permission

telling them they can’t do certain activities

keeping them away from friends or family
