Nikaah & Marriage Issues

Relationship between spouses

Q: How should a wife's relationship be with her husband? To what extent should she love and respect her husband?

I have read somewhere that a man and womans relation should be limited because it harms one's iman the most. I don't remember exactly, but it was something like that.

In my life I feel like sometimes my thinking only rotates around him and his little ignorance or bad behaviour or telling me to improve myself (such as hair, weight, accent, etc.) these things make me so sad that I feel difficulty in breathing. I remain sad for a long time and I cannot concentrate in something. I constantly keep saying that he is bored with me or I am not pretty or he doesn't love me, etc. I know I shouldn't do that. But what should I do when I feel bad that my heart starts to ache? 

Husband sleeping separate from wife

Q:

1. I have a bedroom in which I sleep with my 3 year old daughter. Theres lots of space in my room but my husband does not sleep in the same room as me. Do u think he should sleep in the same room or is it ok for him to sleep seperate from me?

2. Is it wrong for both of us to sleep in one bed as we have children aged 18 to 3 years?

3. Is it wrong for my children to see us sleeping in one bed?

Forced marriage

Q: I was forced to marry a person whom I did not like. I told my mother many times that I dont want to marry this person but my family was not willing to call off the marriage. One night before the nikah I consumed sleeping pills with intention of commuting suicide (Astagfirulkah). The next day I was under the influence of medicine and I don’t remember anything. During my subconscious state my nikah was done with the boy. I was not in my complete senses. I informed my husband about the suicidal step that I have taken and that I don’t want to live with him. Is this Nikah valid as my consent was not given in complete consciousness.

Adoption

Q: We are Muslims and a childless couple. We adopted a baby girl and we don't know about her parentage. We want to give her our name and identity and raise her as our own, without telling her that she was adopted. We don't know who are her parents. Is this allowed?
