2.) Without honesty between you two it will also hinder growth:
Lack of honesty affects not only trust, but communication. It can cause the relationship to be unhealthy. Ever been in a relationship where you meet someone, they ask you what you are looking for you ask them what they are looking for, you discuss the likes and dislikes and compare the similarities and difference etc. Together you start building a beautiful relationship, you both seem perfect for each other, something happens, true colors start to come out who they said they were become questionable. As the relationship heads down hill everything they said they weren’t they become. Well that’s the effect of dishonesty. Most people find out what their person of interest is looking for, they try to become that person. They share with each other what they think will satisfy each other putting aside the real them and say and do what’s necessary to be Mr. or Mrs. Right until they can’t play the role anymore.
Being honest with each other helps avoid a lot of issues. Honesty will open the door to meet, greet and and learn about the real person you’re with. It also prepare you for the tough time, so when their true colors come out you had a glimpse of the portrait already. You can trust each other all you want, but if both of you don’t know the real version of the other that trust is useless.
