I also take the stand that if you don't stop it, then society has the responsibility to intervene and stop it for you, with or without your cooperation. The bottom line on family violence is intervention. The first time is the beginning of the habit. Do not stay and see if it won't happen again. It will not get better by staying in it.
Nobody deserves to be beaten and abused.
And before you marry again, be certain that you have sufficiently worked through the issues that facilitated your mate selection in the first place. Ask them if there is any history of family violence in their family. Family violence is transmitted through generations of learning. If there's an obvious intergenerational pattern of family violence, proceed, if at all, with extreme caution. Also, when you're visiting in his home, pay attention to how his father treats his mother and sisters.
