As for myself, I do believe love is supposed to be something that is easy and not being a burdensome. I have a very romantic sight toward love, where love gives you kind of happiness that could never be replaced. If somehow love makes you feel hard and uneasy, then there should be something wrong with the way you love or how your s/o loves or receive your love.

an object that is not real, complicated, but its existence can be felt

Scary emotion that can change people from A to Z, consciously or unconsciously. It could kill us if we give/get the love to/from the wrong person, but it could be our blessing if we give and get it to/from the right person. The most terrifying gambling I think.
