Remaining unmarried

Q: Is it permissible in Islam to remain unmarried for a girl? I mean I am twenty two years old. I don't want to do nikaah to anyone. I want to live my life without marriage and also being in the ibaadat of Allah Ta'ala till my last breath. According to Islam, is it permissible?

Getting married to a person who is committed to Deen

Q: I love a girl, she is Agha Khani and she loves me too. She sits in i'tikaaf for me. She done all things even hijab. After a few days her mother asked why are you wearing hijab, and my family knows I love her and, her family knows she loves me. Now our families are not agreeing. What should I do?I will do any thing for her. I am facing very big problems. Please help me as soon as you can.

Student loans

Q: Six years ago I applied and received a student loan from Iqraa Trust. At this point in time I was not aware that majority of their funds received is Interest money from financial institutions. My questions are:

1. Have I committed a sin by accepting the student loan without knowing it is interest?

2. Can I repay the loan that they gave me using Interest money?

3. Will students who know that it is Interest money but accepts it as a student loan to be repaid back be sinful?

Make maaf for asking such a question, but after doing some research I found out that their is no Aalim on their board or who is associated with them that could guide me on this issue.
