Haraam relationship
Q: My question is not straight forward but I'll try to make it as concise as possible. I am 18 years old and when I joined college 2 years ago I got to know this person. We started to like each other, he is very God-fearing so he asked me to marry him and make it a halaal relationship for us to be in. So I spoke to my mother and she said she would do something about it and here I am 2 years later hoping for her to still do something. As I am Pakistani love marriages are rare in our culture so my mother did not tell anyone that it is a love proposal. She told her parents and my father that we received a proposal from his foster parents. And because this is the the first proposal they have received they are taking it really lightly and I am not able to do anything other than talk to my mother and ask her to do something but I have tried so hard to convince her she isn't doing anything about it. The person I want to marry is very pious and kind alhamdulilah and his family are as well. I don't know what to do I do not want to be in a haram relationship of any sort because I have only just started to realise the meaning of life and he is the reason I am a better person today. How do I convince my mother, what shall I say to her?
