Back to the idea of being snapped at:

There's only so much stress we can handle before WE snap. When we're trying to be kind and helpful, the last thing we need is punishment for our kindness. There has to be limits to our kindness. We cannot be everyone's doormat. This includes our S.O.

If we allow ourselves to be stepped on, pushed over, and snapped at, we enable everyone else to use us as their punching bag. When we refuse to be victims, the abusers will then stop abusing us. We have more control of our lives than we think.
