Can I marry someone with vitiligo in Islam?

I am muslim, recently married 4 weeks back & work out of India. The girl nor her family disclosed that she has vitiligo before marriage. Post marriage I got to know she has vitiligo & she is taking treatment from 3 years & she now says it's controlled or stable. Vitiligo as we know has no permanent cure & can reoccur anytime in future and passed on to next generation. I was cheated in this matter & hence need divorce. I stayed with her for hardly 3 days & travelled back to work outside India. She is staying now with her family since then. 1. Can I get divorce on the basis of this cheating while i stay out of India & can't come for hearings. 2. Should I initiate the divorce proceedings or wait for her side to start something. The girl is not willing to leave 3. How much time will this divorce process take since it's recent marriage. 4. Will I have to pay for maintenance if I initiate the proceeding of divorce, it's just 3 days we have been together.
