So you tried to be vulnerable in some way, whether it was telling someone how you felt, or asking for what you wanted or needed, or sharing about yourself in a way that felt like “too much,” or otherwise extending an invitation to someone to join you in being a little more human together. And for whatever reason, in some way, it didn’t go as well as you’d hoped. And maybe right now, you feel some combination of disappointed, sad, hurt, invalidated, anxious, hopeless, worthless, angry, frustrated, and/or other feelings you didn't sign up for.
We'll cut to the chase. It’s boundaries, or more specifically, setting boundaries liberally and respecting them consistently.
Surprised? Think about it this way. Boundaries come on a spectrum, which looks different for each person-- there are smaller boundaries, which might look like, “Please lower your voice; my roommates are sleeping” and bigger boundaries, which might be more like, “Please don’t come to my house again.”
What a lot of folks don’t realize is that setting and respecting smaller boundaries are the single best way to avoid the big boundaries.
