4. A BAD PARTNER MAKES YOU APOLOGISE EVEN WHEN THEY ARE WRONG
This happens a lot in so many relationships and it’s just unfair and unhealthy. While a good partner would take responsibilities for their action, a bad partner would transfer the blame.

5. DOESN’T CARE ABOUT YOUR HAPPINESS
The happiness of both partners is important in a relationship. When both partners are happy then the relationship would be better, but a bad partner would only seek his/her own happiness without caring for their partner.
6. THEY KEEP REMINDING YOU OF YOUR MISTAKES
Such a partner doesn’t forgive and clearly doesn’t forget. Moreover, such a partner wouldn’t acknowledge his/her own mistakes.
7. SELFISHNESS
A bad partner is a selfish partner who rarely thinks about the other person — it’s just self, self and self. They regard only their own opinion and make the relationship only about them.
8. THEY ARE MANIPULATIVE
Bad partners are manipulative, in the sense that they only want their will to be done; they think only about themselves, they are controlling and are emotionally abusive.
9. THEY DON’T COMMUNICATE
They don’t try to understand their partner; they don’t communicate. Majority of relationship issues would be easily sorted out if good communication exist between both partners, but a bad partner would care less.
It is essential to have a good partner for the success of a relationship; you cannot have a bad partner and expect a good relationship.
