To still go on holiday by myself after domestic incident

Did you genuinely feel that he criminally assaulted you in a way that warranted police involvement, or did you involve the police as an escalation of your argument to teach him a lesson? Be honest.

Because if it's the former, I don't see how you'd feel safe leaving your children with someone capable of inflicting violence on their family.

He may never have behaved in a way that indicates he would be capable of hitting your children, but presumably he's never hit you before this either?

I would have thought your DH would have been interviewed at the station for a formal caution. If formal, they would notify children’s social care.

I think it's a bit ofd to report a concern to police but then not be concerned about leaving dc with him the next day. Plus won't they be concerned about the incident/police visiting? I would assume they heard something.

Also - I stand corrected if I’m wrong a police caution can only be given if a suspect has admitted guilt . Surely that would have to be in a formal setting under a recorded interview ?

If the police attended there’s no way they would leave allowing him to stay in the property. Also as children are in the property regardless of what you think they haven’t seen/heard the police have a statutory requirement to safeguard the children . So do expect a phone call from the local MASH team and a visit from a social worker . Also if he has hit you why on earth would you consider leaving the children in his care?
the social care team would say that the children are in danger from both parents . From the father due to DV and the mother who walked out to go on holiday with an offender , showing that she is unable to safeguard her children

Do your teens take sleeping pills, are they partially deaf, or do you live in a mansion? Your fight escalated to domestic violence and the police showing up. Parents often have this wishful thinking that their children sleep through their fighting and remain blissfully unaware. It is just that, wishful thinking.

I would go with the kids on my own. This type of behaviour is unacceptable. I get we can all lose our tempers at times. I’m so sorry this has happened to you. Sending hugs. Time away will do you the world of good ❤️

I’m not sure what exactly are you worried about. Is it about him not looking after DSs properly or about the possibility of conflict with violence between him and DSs?
Was he drunk by the way ?
And how did he react to the caution?

You've argued with your dh, it all got out of hand.

What was the argument about? Is he angry that he is being left to look after the dcs? The dcs are old enough to look after themselves for a couple of days, or to call you if anything else happens.

Has he apologised? Are you talking to each other? Or is he angry that you called the police? Do you think the row was engineered to stop you going?

Some space sounds like a very good idea.
