I'm trying to sift through all this... but in Jinouga's case, I'm getting the feeling that her father's death and the mold (which is serious stuff to mess with by the way) in no way effects the rejection. But the woman's reaction and apparent anger/disdain is adding an extra burden to emotional issues already in play.
Which begs the original question: If this woman loves and cares for her so much, why is she making her life difficult when she already knows Jinouga is going through hard times?
Answer: She's being a **** so that Jin feels bad/terrible/etc for not accepting her or changing for her (Oh that little 'power of love' hogwash we're fed as children). Without thought for the other things Jin's been going through.
From the original post, that's pretty much all I'm getting.

Maybe I'm not reading in as deep as ya'll.
I agree that everyone handles rejection differently.
Personally, and away from the issue at hand, I don't care if you've been rejected, you shouldn't react in a way that effects the other person, or any other person, negatively at all. You either grin and bear it in silence or you walk away for a time (or for all time). Having been on the receiving end of rejection I am mortified when I remember my lashing out the first time. I don't
ever want to go there again. So now I just walk away and move on. The lesbian's issues sound like just that
her issues, shouldn't be effecting anyone but herself. She shouldn't be lashing out but rather dealing with her misplaced emotional attachment.
