She didn’t feel any interest in a person who wants to marry her; should she pursue the matter?
Question

                I would really appreciate a reply when time permits inshallah. I sat with a brother that is interested in marrying me. I felt disappointed and bad. Also, I had no feelings or enthusiasm to accept the brother.  Mashallah he has excellent Deen and character. Everyone that knows him speaks highly of him. I guess my question is, how do you know you want to marry that person? Please answer this question inshallah. It is a tough one to find an answer to. Are you just sure? Is there a certain feeling? What if you just don't feel anything for the person at all? (I am not speaking of desire.) Should you marry that person even if you don't feel enthusiastic about marrying them? Also, I only sat with the brother once. Could my lack of enthusiasm be do to this fact?
Praise be to Allah.The Prophet (peace and blessings of Allaah be upon him) said: “If there comes to you one with whose religious commitment and character you are pleased, then marry (your female relative) to him.” And he said, “Seek the one who is religious.” What is addressed to men includes women too. 
When you find a young man whose religious commitment, character and attitude you are pleased with, then you have to accept him as a husband. What will help a girl to do that is to ask about this man from those who know him well, because during short visits, and especially when one is seeking to get married, people are usually on their best behaviour and one sees little of a person’s true nature and character.

A girl may also feel somewhat afraid when thinking of marriage to a person because it is such a life-changing matter. But this fear should not stop you from agreeing if he is religious and of good character. 
We would also draw your attention to the issue of your sitting with this person, which you mentioned at the beginning of your question. If the betrothed couplesit together in the presence of someone who will ensure that there is no khulwah [being alone together], and the woman wears hijaab as she wears for prayer (i.e., covering everything except the hands and face), for a length of time which is sufficient for both parties to make a decision, this is correct and is what is prescribed in Islam; if it is anything other than that, then beware…
