Is it normal that i turned him down because....

ok, this is a slightly long story ..
I met him on a dating website. hes a 30 year old man living in canada while im in australia. i was on a asiandating website and wasnt even a gold member while hes premiere. hes a really , really sweet guy and he treated me real good.hes the kind of man a girl could kill for, loyal, sensitive, sweet...he hasnt been in a relationship since his spanish girlfriend broke his heart five years ago! he told me his life stories and we got really close. we talked for hours. everything was going good . i asked him if he was willing to come to australia to live with me and he said yes as long as he finished his studies.
its just... the first time we saw each other on cam... i had always thought i was attracted to him,personality, looks, and everything.well sure hes a little bit to sensitive and sentimental, but we had so much chemistry that i thought i could totally put that thought aside ight?. but when i saw him... it just reminded me of my first boyfriend years ago. sure they both wear glasses but hes black and my first boyfriend was asian it has never ever occurred to me they resemble each other. speak of my first boyfriend, i was very disgusted of him,not because we broke up,not because hes a bad person,but because hes traits were opposite to what im looking for in a man. blah. i regretted that relationship. i thought its just a random thought. we had chemistry right? its just a random thought... i put that thought aside. but as we got to know each other more and more, i found out they resembled each other in more than one ways.they were, as far as i know, identical twins!i...cringed...and the"in love" feeling that had been enveloping me was...gone.
i finally confessed this to him...and we broke up... i guess maybe we were never meant to be together.
