Victim of a narcissist

Well sadly I’m single today ,had to let go of a woman a genuinely ,genuinely loved with all my heart. It took me 5 months to realize she was actually (and rare in females) a narcissist.I don’t believe I’ve ever been manipulated to this extent and this blindly in my entire life.It is devastating and it will take me a long time to get over it but what choice do I have .
