How does one determine what type of talaaq is issued?

Q: How does one determine that a person issued a particular type of talaaq to his wife. If a talaaq is used as 'I divorce you' how does the poor wife know if this is a talaaq-e-raj'ee (revocable talaaq) or talaaq-baain (irrevocable talaaq). Does it depend on the intention in the heart of the husband and if so how does the wife know which type of talaaq is issued?

Marriage between a Sunni and Shia

Q: My husband gave me only one written divorce (not 3) 3 years back in dubai. After that he realized and made rujoo. I don’t remember after how many days, as I am Sunni Muslim and my husband is Shia, our beliefs are different. I have heard so many times that if a person gave one time divorce and make rujoo (intercourse) then the marriage will continue, I want to know do I have to make any iddat at that time, we don’t know, but if there would be any iddat time then what will I do, do I have to give kuffara? We now moved to Canada one year back from dubai. I will be very thankful as I am very confuse about iddat.
