Love for love's sake

My question for today: Is it pointless to love someone who doesn't share your feelings? I am deeply in love so much so that I can't fall for anyone else because of how deep my love runs for this guy. I hope and pray he will be my husband one day but if not can I stomach him being with someone else or even being alone? I don't know and that saddens me. I hope that one day I will be okay with or without him being in my life until then I am loving the feelings he invokes in me. For now I am just in love for love's sake. That's all I have for today got a final exam to study for so TT4N.
