In what ways she is a lunatic?
Kept suspecting you having other girls outside?
Kept calling you every 5 minute to check where are you?
Kept SMSing you every 30 minute to ask you love her or not?
Sorry, I think I watched too much drama. But sometimes girls or
guys can be too possessive till they act like lunatics. Try to be
more understanding, and spend more time with them, perhaps that
will save ur r/s.
Good luck pal.
