It sounds to me as if the couple had split up. The report says the father is at their former home in Charing, Ashford.
From the father's tweet it sounds like she may have already been emotionally and physically abusing him before they split up which is not nearly as uncommon as some may think.
I dont know how it is in the UK but here almost 1 million 911 calls per year are from men who have been physically assaulted by their female partner.
For a long time in our society males never reported repeated abuses done to them by a female. They are still the least likely to report DV but it is being reported more now.
At one time the police rarely arrested a female for DV assault even if quilty but thankfully that has also changed in the last 10 years or more since LE has had more in depth training concerning DV which is committed by both genders. They have been taught to recognize both can be and often are DV offenders.
I cant remember a case at the moment when a mother murdered her children where the mentally illness excuse wasn't immediately given.
However..I cant remember one case where a father who murdered his children was ever given the same excuse for him doing the very same evil acts.
However..in truth..in all murder cases overall the defendant...both genders...were only ruled to have a mental illness approximately only 2 to 4 percent of the time.
Imo so mothers who murder their own children are no more mentally ill than fathers who murder their children.
In fact the last statistic I read both bio mothers and fathers murder their children as often.
When it comes to gross neglect and horrific abuses concerning maltreatment of their children 59 percent of the time it is done by their bio mother.
So we cant keep pretending it's only fathers or other males who are cold and callous to innocent children. For abused and murdered children to have equal value in all criminal cases where they are the victims we must look at the brutal truth of the offender no matter if they are mothers or fathers or are committed by either or by both genders.
I see this same kind of case quite often on ID shows and often the motive is revenge where the husband/father tires of the constant chaos/ verbal or physical abuse and wants out the relationship but their children mean everything to the father and the mother knows it.
So they begin to plot their premeditated plan to murder his beloved children knowing he will have to live the rest of his life with tremendous pain and suffering and how they died and knowing who took them away.
It's the same motive many fathers have had. If anyone watches all of these true crime cases involving parents murdering their children all the different various motives each one had for doing so are very similiar no matter which parent did it.
