I don't think it burns out. Some people are cowards who give it up due to different circumstances.

The primitive brain needs novelty.

Thats because to love is a choice :) Cant let feelings and sparks do the work alone. Feelings are fickle, my friend.

Love is a choice. I’m not talking about just love. I’m talking about letting a relationship go stale. You can love someone and still settle into a comfortable routine and complacency that kills all passion.

A relationship is hard work.

Some people cannot keep up with it. But for those who constantly give it their all - they are rarities.

It never does with me. Not while in a relationship. And it takes years for me alone to get over an ex.

i feel the same way op. i’m like a delusional romantic cynic. i understand any relationship, specially marriages, take a lot of work. but when people say, the love fades, there are no more sparks, you just have to keep working at it, makes me feel so dreadful and pushes me further into cynicism. committed romantic relationships terrify me, and it may just be naivety thinking, but i would like to think that if i were ever to marry, i would actually want to be obsessed with that person always. like, why, be in a marriage at all if it is seems like hard work and pushing through things ://
