I am a junky for being in love.
I have been in love several times throughout my life, head over heals change my life in crazy ways love. Once in love, I never fall out of love. I can commit to one woman in a material sense, but I cannot be in love with just one woman. I fall in love easily, and don't fall out of love ever.
There is a Sufi concept called Ishq I was recently introduced to. It is passionate ecstatic love that is boundless and without end and is subservient to no rationality whatsoever.
