Transferring the right of divorce to one's wife

Q: My husband and I have been married for 2 years now. We have no children yet. On multiple occasions I caught him cheating on me with some other girl. I know that he is in love with her. I gave him 3 chances already because I didnt want to give up on our marriage. This year I have seen a lot of improvements in him. He has been trying hard to work on our marriage. We went for Umrah as well this past February. I finally felt like things were getting better between us until two days ago. I found him exchanging messages with that same girl and telling her how he feels. They recently started talking again after a year of no contact. I confronted him and now he is begging for another chance and trying to take care of me. He keeps crying to me about how badly he wants me in his life and how much he needs me and how he made a mistake. I havent told anyone about him cheating on me in the past two years but i think i should share it with his mother now. I cant deal with the emotional pain all by myself anymore. I’m going into severe depression.

My question is should i give him another chance? This would be the fourth chance im giving him in two years. Or should I ask for a divorce? I protected this marriage for as long as I could. I dont know if it would be foolish for me to give him another chance. Im breaking down everyday! I dont know what would hurt me more, to stay with him or to leave him. I really didnt want my marriage to end. I dont know if i can live without him. But sometimes i think that if I am still hurting after two years together then i feel like its now my fault for that continuous pain because im the one that keeps giving him chances to hurt me. Please me give your sincere advice.

Divorcing one's wife before meeting her in seclusion

Q: I did niakah with my couisn in 2015 but we never met alone and we never spoke. My father and mother fought because of my father in law. I told them to stop and at that time I loss my mind and I said abusive words to my parents that "you people are dogs, I am giving her divorce divorce divorce, now keep quite. I already gave her 3 divoce so no more fighting otherwise I will do sucide". Then my parents were normal. I said those words unintentionally and I didn't know about the rules of divorce. 

Does saying "we are done" constitute talaaq?

Q: If one tells his wife we are done 2 times is the nikkah still valid? We were not discussing divorce and it was said because she was ignoring me. I said it more out of anger but i know she has a good heart.

She is a new muslim so she is still learning. However later on i found out it was because someone in her family was forcing her to do that in order to ruin our relationship. I have never said the words "I am divorcing you to her" and my intention has always been to help her understand deen. She motivated me to become a better muslim. When i got a nikkah i didn't have a beard. Now i have one and also am a student. Is our nikkah still valid?

Remarrying after khula

Q: I have a elder sister, she had taken a khulanama and talaq e bain as per Indian juridical in the year of 2015 and she also taken a custody of her 3 year son at the time of Khula and from now they are living separate.

Now her husband wants to remarry with her and he is saying I didnt say a word of talaq and since you wanted khula so I just signed and my intentions were not to take khula.

After they get khula my sister didnt perform the iddat period and she is just living a life without a husband.

Now they both want to remarry, can they remarry in Islamic laws.

One more thing, on khulama paper it was written that khulanama and talaq e bain irrevocable what does that mean?
