How to deal with loneliness resulting from being unloved and unseen?

I am 34 Male. Never had a relationship mainly because whichever girl I liked belonged to different religion ( I am a muslim by religion). I started looking for arranged marriage 2 years back. But i am not getting attracted to any matches. I know that attraction is not the factory to be given much importance but it is one of the factors to be considered as I think attractiveness is needed for initial bonding between couples. However, on family pressure I am meeting matches and am getting rejected as i am into yoga and meditation and do not follow muslim practices of praying and fasting. All my friends, to whom I connect, are married and dont have time for me (also, i dont want to burden them for my problems). I am not able to connect to new friends. In my office, I had a crush on a girl (again different religion, hindu), she has been my crush since last 2 years. Sometimes she seems interested in me and sometimes she avoids me totally. Whenever I went to meet matches in arranged marriage setup, this girl is always on my mind. Bottom line, I am so lonely. I can't talk to anyone about how scared I am of being left alone and being unloved. This girl I have crush on, I am not able to get her out of my mind.

Please dont think negatively of me due to me being attracted to a girl of different religion.

How to navigate this situation in my life?
