Healthy relationships require effort and compromise from both partners and involve open communication, honesty, trust, and respect between partners. Both parties in these partnerships are attentive of one another and hold equal positions of authority. Partners share decisions, accept each other's independence, and are free to act independently without fear of repercussions. When the relationship ends, it tends to end more peacefully.
Some characteristics of healthy relationships are:
Respect for both partners
No power imbalances
Setting and respecting boundaries
No forcing to do anything uncomfortable like sexual acts
Respecting wishes
Compromising
Consent
Trusting both parties
If you feel you are in an unhealthy relationship, seek advice and reflect on healthy, safe ways to end it.
