You will never know unless u just ask. be straight forward and ask but what would be better is to get a 3rd party to subtly try and matchmake or do the suggestions and gauge from there if he is interested to pursue this.. better then sitting and wondering.. Khadija(RA) proposed to the prophet(SAW) so there should be no shame in it.. but she did use an intermediary.. u will know your answer and alhamdulillah u will get married and live happily ever after or alhamdulillah you can move on with your life knowing u gave it your best shot.. yes it will be painful if it doesn't happen but that too shall pass and best even now to focus strengthen your relationship with Allah so these knocks don't get the better of you.. see he could either be shy or just not interested.. and u will never know unless u ask.. also when the time comes read your istikharah
