I have no trouble setting boundaries with people I don't care about, and will vigorously defend those boundaries. If someone is important to me, then I usually just hope they don't step on my toes too much. The more I like somebody the more I will keep quiet about it. At some point though I'll pop there head off and kick a field goal with it. That usually leaves them bewildered and thinking I'm unstable. I've lost friends and kept friends doing it that way. The ones I kept didn't cross those lines anymore.
