Joe90, you aren't a "wimp" and this stigma is precisely why domestic violence and abuse being perpetrated BY females AGAINST males is not only underreported, but it is increasing at an exponential rate. 850,000 men report that they are battered each year by their female partners. Of that number, it is estimated that the actual count could be doubled, if not tripled. That makes nearly 2 million men who are attacked and physically harmed by their female partners, each year. This does not even begin to address the emotional abuse that is perpetrated, nor does it address the tens of thousands of men who are murdered each year by their abusive female partners - often, in front of the children who are involved in the melee.
As a Survivor of domestic violence and abuse, I speak from personal experience: waiting around for "something to happen" will forever damage your precious children beyond repair. Waiting around for "an answer" to your situation is only going to shove you further and further down that well of misery - abuse is abuse, regardless of whom the perpetrator is and whom the victim is. Do you want to remain a victim? Do you want your precious children to grow into an abuser or a victim? Do you believe that you don't "deserve" to live a happy, healthy, safe life? I can only tell you that it will never, ever, EVER get better, and the fact that children are involved only makes the abuse even more acute and malignant - to your wife, these children are not human beings, but objects that do not deserve any more consideration than a fly on the wall might garner. You know the answer to your question and only you have the ability to take the steps - nobody is going to take them for you, or your children.
As the father of two innocent lives who had no choice in whom their parents would be, or what kind of environment they would be raised in, I urge you to consider the well-being of your children and yourself, and do whatever is necessary to get yourself, and them to safety. You don't want to "put the kids through" a custody battle? Well, you had better get your head on straight and stop making excuses for not taking the appropriate steps to see them (and, yourself) to safety - it is a solid fact that children who are raised in abusive environments are at extremely high risk to develop into an abuser, themselves, or a victim. What you want, at this point, is irrelevant - it is the innocent lives that matter, right now.
