The police have gone out of their way to assure you that they believe you, honey, as does everyone here and your rl friends have no reason whatsoever to doubt your world.
Given that the police had already made their decision, it's highly unlikely that you were being 'tested' when the DC phoned you to tell you the reasons why your case was not going to be referred to the CPS and I sincerely hope you haven't gone to bed thinking otherwise.
As I've said upthread, on the face of it there appears to be no reason why the police didn't elect to refer your case to the CPS but, from what you've said in your last few posts, imo you should think very carefully before asking your regional police authority to review its decision.
When you posted on being told the police didn't intend to take the matter any further, you were understandably distressed that you wouldn't get the justice you wanted but, shortly after, you appeared to be livelier than you'd been since you beginnning your thread and I'm wondering if this was because your feelings, albeit temporarily, turned to those of anger rather than despair?
If so, I think you will find it far easier to live with the anger of knowing that the police failed to progress your case to the next level than live with the despair of a jury returning a not guilty verdict.
This is not to say a jury would find your attacker not guilty but, even without your phobia of certain words, you would most probably feel that you are on trial when cross-examined by the defence as you will be required to explicity state what he did to you in front of strangers in an open court.
That in itself can be the most horrendous ordeal for victims - many describe it as akin to being rxxxd in public - without the defence implying that their attackers' advances were not only welcome, but actively sought. Unfortunately, you had consensual sex with your attacker a matter of days before he rxxxd you and it doesn't take much to imagine what counsel for the defence would make of that.
Your attacker is cunning. He selects vulnerable women who he suspects will fall victim to his wooing and he brutalises them shortly after he's met with success. This modus operandi is not uncommon and serves to convince me, as I said earlier, that he's done this before and will do it again to other unsuspecting women.
Although he's cunning, he's not clever. One fine day he will select the wrong woman and, as he does not appear to have been formally charged with any offfence(s) against you, it's probable that you will be contacted by the police and play may a part in a successful prosecution which will see him sent down for many years.
Remember that you have something many victims of serious sexual assault do not possess, namely your faith and, although I subscribe to no man-made religion, I would suggest that you give consideration to seeking spiritual direction from your pastor with a view to contemplating the meaning of Luke 22.42 together with Psalms 7 and 55 v.22
Rest assured this ordeal will NOT break you, lovely, nor will it ''finish"you... you WILL come through this and be stronger for it.
