You walked over it

Maybe this is how adults handle "situations". When people just kick your boundaries aside. When someone acts like you owe them kindness and consideration. 

I used to just let people trash my boundaries. 

And then in an effort to protect myself, I cut them off entirely instead. Avoiding the need to communicate. 

And then I learned to communicate, but emotionally. I would raise my voice, stamp my feet. 

And then I learned not to react. Not to say anything immediately. Understand that my boundaries being violated is not a crisis, even though it feels like one. And then say to the person, calmly, that I had a boundary and you walked over it. And then say, calmly, that since you didn't understand what it was, I would spell it out for you. And my new boundary, for you especially, would need you to stand a lot further than in the past. 

Because instead of letting me have the right to my space and my person, you decided what you wanted and needed was more important. Well, I can't control what you do, but I can control how close I allow you.
