She is SEPARATED... not divorced. That makes her still married and to a Middle Eastern Man who (forgive the prejudicial view point) more likely then not, still considered her HIS regardless of whether or not they are sleeping at the same home.
YOU... are also still married even if you are separated.
Get your life in order and your baggage checked which means finalize your divorce so that you are free to date without worrying about unfinished emotional connections. Then, find someone who is a good match who has also stored away all unfinished relationship baggage and is ready to be someone's partner.
This woman IS THE last person with whom you should be trying to ingratiate yourself with. Due to what I've noted above and the fact that she's turned you down before. Move on... nothing to see there.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
