Homosexual feelings

Q: I am a Muslim but I suffer from homosexual feelings. As per advice from many renowned scholars, I got married. I never disclosed this to my wife before marriage. I still have homosexual feelings. So I kept having these thoughts that I have deceived my wife. So I disclosed it to her and she is ok with it as she loves me a lot and I want to stay with her too. I would like to know if this marriage is valid in the eyes of Allah since I hid this truth from her. 

Marrying a divorced woman

Q: I want to marry a divorced girl and she has one daughter also. After marriage her parents will adopt the kid. As per that girl, her family will not disclose anything in front of my family. So, If I am hiding her background from my parents and my family, will this act be bad or good according to shariah as my intention is nikah and reward only.

Taking someone to purchase drugs

Q: I have a Muslim worker who is addicted to mandrax. Daily after work he must smoke. Sometimes he works late and the place where he needs to buy the tablets (drugs) is not safe so he asks me to take him there so that he can go in and buy it and I must drop him home. If I don’t take him, he will walk down and it’s not safe. I have been doing that but it’s bothering my mind, am I not a party to the sin? What should I do? Even though by my not taking him he won’t stop.
