There are two different things here. The abuse towards you and a potential family court for custody of your daughter.
The fact is, if you have left him and don’t intend on getting back together, he can go to family court anyway.
Yes, reporting to police won’t mean they turn down 50/50 unsupervised, yes, it seems strange, but, he is abusive towards you but not to your daughter (witnessing abuse is obviously emotional abuse but, by not being together, that is managed)
Has he been abusive towards her ever? If not, you’ll have no legal reason to keep him from seeing his daughter, family courts look poorly on a parent stopping the other from seeing their child without ‘good’ reason. If he has, however, that’s a different matter, you can exercise the right to parental responsibility for safeguarding your child, can report this to social services and they may choose to investigate. They would speak to your child to get her views.
So, the fact is, he can take you to family court whenever he likes, regardless of you reporting the abuse.
However, as he is also claiming abuse, you are going to have little credibility in family court on any level, if you claim abuse but didn’t report to police. It will be hard to look like you are not just a bitter ex keeping your child from her ex and claiming domestic abuse maliciously.
In summary, no, reporting won’t guarantee that he doesn’t get custody, however, it will make you more credible should you end up in family court.
Best advice I can give is, report it, have your dad with you when they come to take a statement as he can also show that he admitted it. Also, the text where he said ‘it wasn’t that bad’ is pretty damming evidence that he did, indeed, attack you.
Perpetrators rely on control and fear. That’s exactly what he’s doing right now, making you fearful of losing your daughter. He will go from horrible to lovely and want to tempt you back. Then it will all begin again. It’s called the cycle of abuse for a reason.
You’ve done the hardest bit by leaving him, please report to police and strengthen your case against him. How long were you with him? You can also request a Claire’s law, there may be past police reports which will also strengthen your case. Ask the police for this too.
If you do the above, IF it goes to family court (if it’s does, it may not, it is very expensive and the person making the application has the biggest bills- classic perpetrator threat is family court) then you will be able to evidence you are a mum whose priority is to safeguard your child against emotional abuse by not witnessing abuse and taking the appropriate steps to ensure it never happens again. If you don’t, you will not look so credible and leave yourself more vulnerable to his lies.
It’s not easy, but you have done the hardest bit, m power yourself to feel more in control. X
