Nikaah & Marriage Issues

Q: I am engaged to my cousin from last 2 years, we have 10 years of difference in our age. We are dying to get married with each other but our parents specially my fiance's parents are not willing to marry her daughter till 8 to 10 months more. My parents are ready but the girl's parents are saying that we are not in a position to arrange money for marriage. My age is 31 now and I am losing control on my patience. I am afraid of going on wrong path if I dont get married till next 3 months. Please tell me weather girl's parents are doing correct thing by holding our marriage?

Q: I wanted to know that if a person is aroused by thinking of something else or seeing someone else but his mother in law is sitting next to him but he is not aroused by her in anyway nor is his attention on her but because they are sitting next to each other both body is in contact. Does this count? Also say you touched a woman with lust before marriage. Can you marry her daughter?

Q: A born Muslim girl is married to a Christian boy with her fathers consent. Her father (our close relative) told us that his happiness lies in his childrens happiness.
