Writing "I will give you talaaq"

Q: I would like to know if talaaq given via sms is valid because I was very angry and upset and in so much of doubt and confused and I was influenced by my friend to do it and he told me to just do what he says. So being in that state of mind I was not thinking properly so I wrote "I will give you talaaq (islamic divorce) and sent it and after 2 days later he said must do the same send another sms and again 2 days later another. He didn't explain about talaaq to me and about the iddat period and the time to reconcile between each period. I got different answers because people say sms is not valid and if influenced by someone to do it then it is not valid. So I would appreciate if you could shed some light on this topic. We want to reconcile and work things out but not sure where we stand because there is a lot going on.

Going to dargaahs

Q: I am married for 6 years and I do not have children. My mother in law wants me to visit a dargaah and pray there. I have faith only in Allah. He knows better what is best for me. Should I go or not? I am undergoing IUI treatment. Can I continue this?

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.)
