Is it normal that i like my cousin

when i was little (i think 9 or 8 years old) me and my cousin liked each other a lot. we kissed and sometimes when she would sleepover we would sleep in the same bed and kiss all night.we also got naked while we slept. then she moved away for awhile and 7 years later i saw her again i was instantly attracted to her. but i don't know if she remembers what we use to do and I'm too afraid to ask her. she's always been nice to me even though i've been trying to distance myself from her, but every now and then i think about her and i wish i could tell her how i really feel.
