You cannot always blame the parents. 
There are many factors involved in why a person is the way they are, not
the least of which you would understand as karma.  If you want to blame the parents, go back to
the time before the birth of even the parents when the soul group was deciding
who would be related to whom for the greatest learning.  Now are you beginning to see? 
You signed up for each other for the growth
of the soul which could potentially occur as a result of your
interactions.  And now you are facing
those growth opportunities.  Ah, yes, you
might choose to call them “challenges.” 
Whatever term you use, we are aware that it is not always easy.  It is the very difficulty of the choices you
face that actually makes it easier to notice when the opportunity to bring love
into your choices presents itself.  Do
you see?  Major challenge?  Major opportunity to respond with love.  Oh, the beauty in the system when you can see
it as such.
