Dear Wanttobehealthy, it is important to keep a very detailed journal of these events. Dates, times, any witnesses, any verbal threats---everything. This could become invaluable in the future.
Talking with the local domestic violence organization counselor can help you. They deal with this all the time. You can remain anomyous. Also, talking to the lawyer is a must also.
Do not try to go this alone. There are professionals that know how to guide you. You need all the help you can get to keep you and the girls safe.
You have shown great strength---but, do get yourself some help.
Many on this board have been through this kind of H***. Keep coming back. You are not alone.
