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? 

Q: I have an adopted girl (minor). I want to perform my Nikah with her. How can that be done as usually its the guardian that would do this but I am the guardian.
