a flood of abandonment- the cost

A partner or loved one says "I want to do that alone" . If my mind believes that THEY WANT TO DO IT WITHOUT ME, it is prone to start looking at longing for them to include me or want to stay. I feel hurt and rejected, and ultimately so alone. Why did they said that, what did I do wrong, and ultimately wondering if I matter or have value. It's easy to hide or ignore the person, holding resentment. Through Inquiry I begin to open to possibly reasons they may want to go alone, how it may be good for them which is ultimately good for me, and then I hear Katie ask, "How have you been spared?" What gifts await me staying? What gifts are hidden in our separating, living on our own for this phase? And ultimately- is it possible for them to ever be without me?
