Eddie what you are saying is, I'm afraid, incorrect.
I think there is very little chance the CPS will not proceed with the case if you retract your statement and you must get legal advice before doing so and I think it is extremely unwise, but this is their official guideline on retracted statements during domestic abuse cases.
This from the CPS:-
Retractions and withdrawals by complainants
It is possible that a complainant may ask the police not to proceed any further with a prosecution case and say they no longer wish to give evidence.
There may be a number of reasons why a complainant will withdraw their support from a prosecution, or retract their allegation, but this does not mean that the case will be automatically stopped.
Prosecutors may see any of the following as possible reasons why a complainant may no longer support a case. This is not an exhaustive list, but should be considered as a means to assist prosecutors in understanding how they will need to consider the next steps to be taken:
fear of other offences being committed, or risk of further harm (both in person, but also through online technologies);
fear of coming face to face with the abuser in court;
pressure from the perpetrator, the perpetrator's family or associates;
fear of repercussions that may follow from peers of the perpetrator, or gang members where either the complainant, perpetrator or both are involved in a gang;
pressure from other family members, other members of the community or community 'elders', including being pressured to resolve 'differences' between parties through mediation, or arbitration tribunals conducted within the community;
fear of being publicly shamed, disowned or outcast from the community;
a wish to be reconciled with the perpetrator, if not already reconciled, or a wish to return to the family, if estranged;
the complainant is no longer in a relationship with the perpetrator or does not want to re-live the incident;
a fear that children will be removed and placed into care, or not wanting to be perceived as 'being difficult' if children or other dependants are involved;
a fear the of impact on children, or other dependants, or financial repercussions (such as the receipt of certain child maintenance, tax allowances or financial support through benefits)if the perpetrator were to receive a custodial sentence;
continuing with a prosecution may cause the complainant to feel they are responsible for the perpetrator receiving a criminal record and the impact on their job and family finances, etc;
the perpetrator may agree to drop other proceedings such as custody applications for children, if the complainan withdraws the complaint;
embarrassment at reporting the complaint(as a result of the complainant's or perpetrator's social background, or for example, in cases of child to parent violence);
fear they may not be believed and fears that the criminal justice system is biased towards the offender;
feelings of isolation or vulnerability, and fears they may not be believed as a result of those vulnerabilities;
fears that showing support for a prosecution may place them at further risk of harm;
fear of immigration status being made known to law enforcement authorities, or fear that a complaint may reveal the perpetrator's immigration status which may not be secure;
fear of being 'outed' about their sexual orientation, or gender identity if not already known about;
fear of HIV status or other very sensitive personal information being revealed if not already known;
where complainants are involved in prostitution, fears that any previous contact with the police will result in their complaint not being taken seriously;
