Good luck in the path ahead.
As a rule I am a non violent person, but domestic violence pushes my non violence to the limits... there is NO EXCUSE that can ever be used to defend such a person that hits another! You are obviously better off out of that situation.
Read your blog post. Buddhism is a difficult path and I wish you well with it. If you do wish to follow that path then at some time you will need to let go of the anger you feel, but this will take time and hard work and meditation. I can tell you that for me my life changed when I let go of the anger, it is the first step into a bigger and better world (IMG:

You may find the audio dharma talks at

Be well.
