When you say: "....don't you dare try to set a boundary, and not exemplify to your W the man you are trying to be!", what do you mean?
That means set firm boundaries that are clear, but as you life your life be honest, sincere, clear, appropriately loving for your situation, living above reproach. Or as many like to say, CHD. Courage. Honor. Dignity.
You can't expect to have boundaries respected if you don't act in a respectable manner.
I'm not implying that you aren't already doing this, just offering encouragement, as it's easy to forget in the swirl of emotions.
