Answer:
(Fatwa: 187/189=L)
If you have spent time with your wife in privacy, then in the abovementioned case the three talaqs took place and your wife was divorced with mughalllaza (irrevocable) talaq and now you cannot rejoin without Sharai Halalah, as the Quran says: فان طلقھا فلا تحل لہ من بعد حتی تنکح زوجاً غیرہ (الآیۃ)
Now, she will have to sit in iddah (waiting) period, she can marry a man after the iddah is over. If he is divorced again by this husband and spends iddah period, then she can marry his first husband.
