if this is really what u say, this sounds extreme to me.
if she is really so unrational, for a short term measure, my
suggestion is not to speak to her for 2 weeks, minimise seeing her,
try to get home late until u know shes asleep. and avoid going out
with her. and see whats her reaction?
at the same time, talk to ur dad about it. and see what he says.
she might have some problems u dun know about. i always believe in
looking at the core of the problem then think of a solution~ u want
a long term measure.. nto a short one..
