i apologize in advance if it's not my place to say.
we can't always expect someone to stop doing things no matter how we tell them not to. and we can't always expect the situations to change according to our will. what we can expect is how we react to it.
while you haven't found a new way to stop her, let's find a way to fit yourself in the current situation. let's find a way, whatever it may be, to survive and stay sane in your current situation right now.
because we choose our own happiness. and i think it applies to staying sane too. we choose our own ways to stay sane.
and i don't know whether you believe it or not or whether you already knew about this or not, but speaking about your looks, you're highly attractive!
