السلام عليكم, Sister Hirah, I hope you will forgive me for being frank. From your description, it seems there is one thing on this guy's mind- and this is generally the case with every impious man- and he is just using this talk of religion to get "with" you. This is a very common game played by men of this type. Every man knows that the safest way to capture a woman's heart is through a show of respect and niceness. But if he really respected you, then wouldn't he be lowering his gaze and honoring your chastity? If he was really nice, wouldn't he be treating you with honor rather than trying to get you to meet him? And the feeling that you get that you will be able to stay away from him on account of your natural shyness is a trick from Shaytaan. You can't depend on "changing the subject" forever, eventually he may find a way to meet you, and then that same shyness will make it difficult for you to say no to him. And even if by some coincidence you never meet him, this will not stop Shaytaan from putting evil thoughts and desires in your heart because of him. This may lead to some other sin, and May Allah protect all of us. How great is Allah's mercy upon us! He hasn't just ordered us to stay chaste, but he gave us instructions to mold our lives so it will be easy for us. If you look at false religions like Christianity, they are going to great lengths with all kinds of programs, vows, rings, etc. to stay chaste, but in the end the fall into it anyway on account of their lifestyle. We have this beautiful deen that tells us the small things we have to avoid in order to make it easy to avoid the big things. And we should consider all those "small" sins as very serious, not looking at what anyone else is doing, but keeping our eyes on the greatness of Allah. So, I concur with the sister who is recommending for you to "run far away." You don't have to be rude, but be firm. I would suggest that maybe you should contact some pious Muslim boy to go and ask him if he has any questions about Sunni Islam. Then if he tries to contact you again, ask him if he talked to the person you sent and that he will be able to help him understand Islam better than you can. Then tell him politely but firmly that you can't talk with him anymore in private- as you are in love with someone else who will be angry if they find you speaking to another boy in private- Allah and his messenger! Remember that if you please Allah, it won't matter if the whole world seems angry with you and thinks you are rude. And if you displease Allah, then the whole world can be friendly with you and you would still be ruined- Allah protect us. Maybe others who have had experience breaking off relationships like this can offer suggestions and encouragement.
