If I could tell you the answers to all the 3 questions, I could also tell you the name and address of your prospective bride too. You just only have to go and knock at her door and she will come with you.
Please read the articles on this site written by me and also on http://navagrahastro.blogspot.in/ after which you come back with more realistic questions about marriage.
Nobody human can predict answers to such questions except perhaps wayside astrologers near India gate or at the banks of Ganga. Astrology can only tell you your success factor in marriage or in other words your marital bliss and happiness. Even the definition of marriage is different in Astrology. When you read the articles, you will better understand what astrology can do and what not.
