There has been violence in the marriage. It doesn't really matter which of you files for a non-molestation order or an occupation order, there would be a court injunction in place and it would potentially have an arrest order attached to it. Even though Police NFAd it, there is still evidence there. An occupation order would give her (or you) the right to keep the other away from the property.
Is this really the route to go down? The chances of your kids not getting embroiled in this are next to non existent. Are they going to be okay with seeing Mum or Dad removed by the Police? It isn't an idle threat; she's called before.
Abandonment is not an issue in any divorce proceeding; it simply helps to show an irretrievably broken down marriage (the only grounds for divorce in the UK)
If you want an alternative opinion; forcing yourself back into the marital home against the other persons wishes on a background of domestic violence smacks of bullying and harassment. If I were the W it certainly wouldn't make me start to change my mind, but confirm everything I think I know about you and the marriage already.
Let the dust settle; emotions are running too high. Start DBing like mad and show her the changes are permanent.
