Ruling on gifts that she received through her relationship with a man before she got engaged
Question

                I have a computer, mobile phone and other things all of which came through haraam means, in the sense that I had a relationship for a while and he gave me these things with no ulterior motive or bad intention. The evidence is that he proposed to me but my family rejected him. What I mean is that he gave them willingly and always regarded these things as belonging to me and not to him. 

In the end, the relationship came to an end, praise be to Allah. But I want to ask about the ruling on my using these things and the permissible way of using them. 

Because I know that that which is built on falsehood is also false, but I do not know the ruling on that. 

What do I have to do ?? 

Also: if I give in charity or donate my money, or if I use anything, I have my doubts about this money because it is mixed – some of it is from my own wealth and some of it is from this relationship, and some of it is in the form of shares. 

Also, I do not know whether what I put into shares was from me or not. There are many things I am confused about with regard to these matters, and I want an answer so as to put my mind at rest. The wealth will disappear sooner or later, but what has gone I will be asked about on the Day of Resurrection. And you know and everyone knows that Allah is good and does not accept anything but that which is good.
Praise be to Allah.
      Firstly: 

    It is not permissible for a woman to form a relationship with 
    a man who is not permissible for her, even if it is with the intention of 
    getting married in the future, because these relationships involve things 
    that are haraam and wrong, such as looking, touching, enjoying listening, 
    infatuation, soft speech and other things that are not pleasing to Allah, 
    may He be exalted. 

    Secondly: 

    The gifts that you received are subject to further 
    discussion. 

    1.Whatever was taken in return 
    for the haraam relationships that involved the evils that you have 
    mentioned, if it is still with you then you have to get rid of it by giving 
    it to the poor and needy. Whatever has been used up or spent, you do not 
    have to do anything with regard to it.

    This is the basic principle with regard to the one who has 
    acquired wealth through haraam work and it was given to him by the other 
    party willingly, such as payment for singing and dancing and the like. The 
    money should not be given back to the one who gave it, and the one who took 
    it should not benefit from it because it is wealth that he took in an evil 
    manner. 

    The gifts that men give in haraam relationships are only 
    given in return for enjoying the continuation of that relationship, seeing 
    the woman, going out with her, talking to her and so on. They are given 
    willingly in return for something haraam. The most correct scholarly opinion 
    on that is what we have mentioned, that one should get rid of them. 

    2.Gifts that came after 
    engagement; if the fiancé asks for them, they must be given back to him, but 
    if he does not ask for them then they become your property.
