Here are some of my personal deal breakers...

🚩 Any kind of abuse or violence.

🚩 Cheating in any form

🚩 Dishonesty 

🚩 Mind games

🚩 Disloyalty 

🚩 Poor communication 

🚩 Ghosting 

🚩 Active substance abuse

🚩 Cruelty to animals

🚩 Cruelty to children 

🚩 Unkind to people 

🚩 Extreme emotional immaturity

🚩 Makes it all about sex

🚩 Intolerant of different points of views

🚩 Is racist, ableist and otherwise intolerant of people of different backgrounds

🚩 Isn't over their ex and still pining for them
