Certainly not what God intended when he said two people should become as one. God never intended for you to be abused. Emotional and verbal abuse can destroy a person's life. Women tend to stay longer in an abusive relationship when the abuse is mostly emotional rather than physical, but the result of a long term emotionally abusive relationship can be severe depression, hopelessness and even suicide. Marriage counseling is not usually recommended for cases of abuse.
Abusers have a huge problem realizing that their behavior is a problem.
Usually, abusers have a very difficult time changing, if they are able to change at all. Personally, I feel 29 years is a long enough time to wait for things to improve. You are entitled to some happiness. Abusers are generally unhappy people, but you shouldn't have to suffer, too. There is an excellent little book written for Christian women in abusive relationships.
