We, friend, have a responsibility to teach people what is and is not acceptable. We have a responsibility take care of ourselves first. It is okay for us to have wants and needs, and for us to express these things out loud. It all comes down to what we believe we are worthy of, and what we choose to allow or permit.
If someone hurts me, takes advantage of me, takes me for granted, is insensitive, rude, or fails to value me, it is my responsibility to speak up. Space in my life is valuable, and if you want to occupy a portion of that space you better rise the f*ck up, because I no longer have time, energy, or f*cks to waste on takers, manipulators, or liars. If showing you my boundary freaks you out or makes you feel I am demanding or needy – there is the damn door.
