Hi Taya,
I was involved in a physically abusive relationship in college, and what gave me the courage to end the relationship was going to counseling. My counselor was very kind and understanding and helped me find the resources I needed to get out of the situation (new housing, etc.). Also I attended group sessions and it was wonderful just knowing that I was not alone. If there is a battered women's shelter in your area, you can call them to get a referral for a counselor or group sessions.
Please do not delay - the longer you stay, the longer your daughters will think that this is the way things ought to be. You, and they, deserve better.
Best of luck to you. Stay strong.
