Conditions for the validity of Nikaah

Marrying a revert

Q: I was married with a husband who had converted to Islam 7 years ago but our marriage lasted for 2 years and we separated due to misunderstandings even though not officially divorced because he doesn't want to. During our marriage he didn't want to pray or fast sometimes even saying he will pray when he is with my family. My question is: Was my marriage valid? Should I ask for a divorce and sit for iddat even if we separated 5 years ago?

Mut'ah

Q: If a man and a woman plan to get married just to satisfy their sexual need. Further more they have decided to get separated by divorce afterwards. Are they committing a sin?

Marrying a Christian

Q: I married a Christian girl and conducted the Nikah myself - i.e. I got two non-Muslim witnesses, asked her if she accepted my proposal based on the Mahr I gave her, she accepted and I then read the Nikah Khutbah, and confirmed that I have accepted her as well in my Nikaah. First Question: Is my Nikaah Valid? Secondly - things did not work out and I have subsequently given her 3 Talaaqs telling her that I divorce her in front of two Muslim male witnesses. If she reverts from Christianity - can I remarry her (perform Nikah again) or not? (Does she first need to remarry someone else etc.)
