He got to know a girl through correspondence and wants to marry her, but he is confused by the contradiction between some fatwas about getting married in this way
Question

                I am looking for some advice about what I should do with regard to the girl I want to marry, but our relationship began through correspondence on the internet. I looked at the fatwas and found that some fatwas say that there is nothing wrong with that once it is established that the woman is religiously committed and her family are good. But I found other fatwas which warn against getting married in this way and say that it is essential to avoid it completely and cut off all ties and not get married in this way. 

What is the correct opinion, based on the Qur’aan and Sunnah? I hope that you can answer this question in detail because I am sure that many people are faced with this problem today with the increase in communication through the internet. May Allah bless you all.
Praise be to Allah.
      We have to differentiate here between two important matters 
      with regard to this issue. 

    -1-

    The ruling on this correspondence between young men and young 
    women, and entering into relationships in which they get to know one another 
    and talk to one another. This is something that is haraam. We have drawn 
    attention to this prohibition in several answers which you can read on this 
    site. 

    It cannot be justified by saying that the intention of one or 
    both parties is to look for a suitable partner to marry. This is looking in 
    an unknown world where it is not possible to verify any of the 
    characteristics that the suitor should be looking for, let alone the lack of 
    the required seriousness when the matter is approached in this way, and the 
    lack of honesty in describing the characteristics of each party, and other 
    matters which anyone who has approached this matter in this way knows. 

    -2-

    In the event that this has actually taken place, i.e., where 
    a person has started to get to know someone -- whether that was because he 
    did not know that such relationships are haraam, or because he thought that 
    the good intention (seeking a suitable spouse) made it permissible, or he 
    embarked on it as most people do, without paying attention to whether it is 
    halaal or haraam, or because he was following his whims and desires -- if 
    the person in such a situation asks us whether he can go ahead with this 
    marriage or not, the answer is:

    In general we do not advise these kinds of marriages, because 
    the element of certainty with regard to the information acquired about the 
    other party is not present; rather it is information that each party has 
    given about himself or herself, which may lead to infatuation between the 
    two parties before it has been established whether they are suitable for 
    marriage or whether they have the qualities needed for a successful 
    marriage. 

    But despite that there may be some cases in which going ahead 
    with marriage may be acceptable, despite the fact that the initial steps 
    towards the marriage were wrong, as they came about because of ignorance of 
    the ruling, as we have said, or because of a mistake which was out of 
    character for the individual, and it has been possible to find out the 
    necessary information about each party. In this case it may be acceptable -- 
    in certain cases -- to go ahead with a marriage that started in this manner. 
    The permissibility is further confirmed if the attachment to one another has 
    become so strong that it is difficult for them to be separated. In this case 
    we advise them to repent from this haraam relationship and they should be 
    reminded to adhere to the commands of Allah, then there is nothing wrong 
    with them going ahead with the marriage. 

    And Allah knows best.
