Man there is Love all around us.

U can't confine Love some with some mere definition.

And to answer one of ur curiosity, ya one can love someone and marry someone else, it is perfectly normal. I don't know who gave u the wrong impression that every Love should end in marriage.

Love is a feeling a lively experience while marriage is an institution.

And u don't have to limit your love to 1 person. If u have love in u then spread it, that is the best thing to do.

As our poet Madhav Ghimire wrote once :

"Aayera kahilei Rhitu Shidhhidaina

Laayera Maya Mutu Rittidaina".

SO don't worry about what u see go ahead to feel it. To be loved is the most awesome experience in your life so go get it and don't forget to spread it.

Take Care.
