Assalam o alaikum

i have been in nikah for more than 8 years, since my nikah i have never been in a sexual relationship with my husband (as he never ever wanted to) but only kissing and hugging and thats it. my question is if i get divorce from him, will i be due to any iddah? please do reply as soon as possible.
also we have been apart for more than 4 years (never seen eachother's faces) i am alway told by everyone that i am not his wife anymore and i am free to nikkah to somebody else, please let me know what is right and what is wrong.
may Allah swt give you peace in this world and the herafter.
