At least Jesus isn't going get a girl pregnant and abandon her, give her an incurable STD, or beat her up, like other potential love interests.
But seriously, people make the exact comment you have made all the time, but nuptial/romantic imagery for the soul's relationship to God is one of the many poetic expressions found in Scripture and in the writings of the saints from the earliest days of Christianity. It may not be to everyone's taste, but Christian worship isn't about everyone's sharing the same tastes.
Some people aren't going to like you saying that. It's true though. :)
I think part of the problem is that people equate love with eros and only with eros today. It is why every book that has a strong male friendship in it is now taken as being "gay".
Love is also agape, philia, and storge but popular culture has so influenced people that when they hear someone sing of their love for God that they automatically make it into eros. The fault is not in the song or the singer but in the mind and heart of the listener.
