I had a friend ask me if love hurts or causes pain. My response was that love itself never hurts or causes pains, yet the situational context in which you present love and the things and people you may attach your love TO may. For example in unrequited love, it is not the love itself that is at fault, but the unidirectional nature of the relationship. Unless the love is disconnected from such a toxic situation, the resulting psychological, emotional, and likely financial sinkhole will make the loving party feel great pain, sorrow, and trauma. The route to pain free love is approaching love with an understanding of love as selflessness, but mutual love as reciprocity. Love in a relationship context is selflessness mutually reciprocated.
