وعليكم السلام ورحمة الله وبركاته
May Allaah Ta`aalaa grant you relief from your difficulties, Aameen.
Matters of Nikaah (marriage) and Talaaq (divorce) should never be handled over the internet. Those are matters which must be dealt with in person. If you are already living separately then the danger of Talaaq is imminent. What you need to do is to speak with her and also speak with family. Make amends. Get in touch with an `Aalim in your area and seek advice from him (in person) as to how you should go about doing so. Explain to him your situation with all of the details so that he is in a proper position to give advice. Also, if your parents are still alive, consult with them, and also with wise/experienced members of your own family.
Was-Salaam.
