Q: Is it better to have more than one wife in islam? As in Quran the ayat starts with marrying two or three or four. If they cannot be just to more than one, only then they should marry one. And our Prophet and all the Sahabah (as far I know) had more than one wife. So is it more appreciated in Islam to have more than one wife?

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 would like to know if I can speak to my wife by implanting thoughts in her mind to love me without her realizing this consciously to improve my marriage. These techniques are taught in NLP Neuro-linguistic programming which teaches people how to use language to influence others by saying a sentence in a way where you are telling the mind what to do. For example, instead of saying you should love me, I said to her you can feel yourself loving me more and more now. Is this permissible for me to do?
