Whenever I took contrary action, I found out why I had never taken contrary action by myself......all kinds of negative feelings flooded me.
The simple truth is that people I love don't like not getting their way. When faced with a simple, "No," they reacted. I hated the conflict, which is why I never said "No" before.
Don't worry. Not only will you get stronger in the face of conflict, but others will also come to respect you more and their own behavior will change. It works out just fine.
This is called......."boundary flack." Expect it for awhile.
You did great!
