Forcing a boy to get married

Q: I have an important question which I would like to ask on behalf of a friend of mine. I shall explain the whole situation and would like some Islamic advice on the matter.

Basically one my friends family have taken him to Pakistan to get married to one of his relatives there, at the time of his travel he was unaware of this. My friend likes somebody else who he would like to marry but due to his family pressure and everything he has unwillingly got engaged to his relative from Pakistan although his heart is still with the girl in UK whom he loves and wanted to wife. The girl and him have mutual feelings and still want to be together, he is not willing to forget this girl and claims he still wants to be with her, but his family have trapped him into this wedding which he is not happy with. I would just like to know on his behalf whether this marriage which was forced upon him is considered valid in Islam, because a few islamic websites I have checked on have said a marriage which is forced or not the happiness of an individual it is not valid in Islam's and Allah's eyes, is this true?

Also would it be appropriate for my friend and the girl he loves to still stay in contact regardless of this marriage which has been conducted without his happiness? What would be the best Islamic way to tackle such a situation?

Court divorce

Q: I am a female who is legally divorced in USA for more than one year. My ex husband went to a Shariah board 3 times during this divorce but refused to give me an Islamic divorce. During the marriage, he refused sex and any kind of relationship with me. He has not touched me for more than ten years. Am I still under his nikkah?

Adult daughter sleeping in the same room with parents

Q: Is it ok to put my daughter's bed in my own big master bedroom as there is no physical relation between me and my husband due to perpertual illness of him. My daughter is an adult but still childish and since I have heard stories in my own family of jinn coming on my young virgin niece and talking to her as she was left alone in a separate room, I am hesitant to make my daughter sleep alone in another room. She has no siblings. It is only the 3 of us.

Making dua after nifaas

Q: Relatives are telling me that when my 40 days of nifaas (postpartum) are over, my husband should make a prayer or dua as it is what the elders have done. I am asking if this is stated in any hadith and if it is required to do so.
