Unfortunately, the “loving and apologizing” behaviour is just part of the cycle of violence. Tension builds, the violence erupts, and then the abuser is often remorseful and promises to “do better” - until it happens again.
The evidence suggests that over 80% of children who are exposed to violence and abuse, even if it’s not directed at them, are affected by it. Do NOT continue to expose yourself and your children to this woman.
I’ll give you the advice I generally give to ALL people who are being abused:
- Recognize that this is NOT your fault. Statistically, as a man, you are in the minority of abuse victims, and this can be very difficult for men to accept. She’s not beating you because you’re a “sissy” or you can’t control her. This is HER problem, NOT yours.
- Squirrel away as much cash as you can. Cash is usually better than plastic because it can’t be traced. Plus, if you have a joint account she could freeze it, or she could attempt to cancel your credit cards (particularly if they’re joint as well). She could also attempt to have you traced through your plastic. She can’t freeze cash and she can’t trace it either.
- Put together important documents, such as your children’s birth certificates. I also strongly encourage that you keep a record of her violence - this could be important to present to the police, especially because you are a male victim.
- Phone a domestic violence shelter or hotline. Then call an innocuous number, like the Weather Network or something, afterwards so if she presses “redial” she doesn’t figure out that you sought help.
- See if you can find services geared specifically towards providing support for battered and abused men. Many services are geared towards women, because statistically women are the most common victims. However, you might be able to find something that will meet your specific needs as a male victim.
- When you do leave, it’s best not to go to a friend’s house or a relative’s house. It could be very easy for her to track you there. It’s often best to look into a shelter or a protected accommodation, especially one that has good security.
- Be EXTREMELY careful after you leave, particularly because there are children involved. If she hasn’t legally adopted the children, my expectation is that she should not have legal rights to them - stepparents usually don’t, though please, please, please consult a lawyer about this, particularly because the children’s mother is deceased. In the meantime, be very careful about school. Make sure the school knows who is and is not allowed to pick up the children, and make sure they understand that their stepmother is NOT to be picking them up. Sadly, abuse tends to escalate towards homicidal violence when a victim tries to leave. Your children have already lost one parent - the last thing you want is for them to lose the other, too.
For the record - I think somebody said something about a kettle. It wasn’t a kettle she was threatening the OP with, it was a kettle bell. This is a Russian weight that’s shaped like a flat-bottomed ball with a handle on top. They’re used for weight lifting and, depending on the weight, could kill someone if you got bashed in the head with it. Make sure you write down that she said that, and record any future threats, as a PP suggested.
