Go to mediation or your church group for help. Please do not retain a lawyer . Its another trap. You are giving up your right to think for yourself to them. Sorry - there's more.
Abuse is a serious matter.
By no means do I advocate physical or constant verbal attacks. This is not right. Too many people fall into the trap of feeling like a victim in a marriage and then subscribing to the Feminist concept of what abuse is. Society in their effort to be politically correct has give into the feminist notion that it is always the mans falt and the women is always the victim. Remember it takes two to make arguements and it takes two to work things out .
