Taboo crush with niece

So, I'm 35 years old & have a crush on my 27 year old [half in law] niece. 7 years ago, she took advantage of me [as an adult] and continued to do so for about 6 months. Despite all efforts in searching for a partner, I've had zero success since 2008. She used to fuck me & bite me during and was very sexually versatile in stances and what-not. Every day now for the past few months, all I can about it her. I love her passionately with all my mind body & soul. She's fixed with kids, so I see no genealogical potential problem arising. I've tried all places to find an alternative, from high to low places, but with absolute zero results & success. I've begged God for a matching mate, but with zero results whatsoever for over 7 years, so I'm thus convinced at this point that she is my soul mate. Is it okay for me to pursue her!? Anyone I date is a flop insofar as matching internally. I think of her romantically every day like I'm on fire like the fusion of the sun!
