Sociopath Community

 I think relationships in general-- the social dynamic gives us a "meta" that can give us something to work toward each day of our lives because social status is a goal that can never really be reached completely. 

 It's almost as if the Human mind never evolved to exist in a society where basic human needs weren't the key motivating factors in the individual's every day life.

 Her lyrics say it exactly!

"Tell me love isn't true, it's just something that we do."

Love == Our reason for living

Our reason for living == Our Relationships

Not a single relationship, but all of them.

Love and pleasure from it is actually a bit more complex.

Procreation is important for keeping most species from dying out. Each one has their own reasons for going about it, usually as a form of instinctual response to things like scents. We as humans however have the burden of awareness, so instead of just acting on our urges, we have all sorts of weird ways of going about making it happen. This however doesn't mean those urges aren't still there. As people, having to put meaning behind everything we see and feel, we naturally give everything names. When said feeling lasts for an extended period of time, it has been labeled as "Love".

Love isn't a choice, it is a passionate response. You can't just look at someone and go "Yeah, loving that person seems like something I should do", it just happens. Love can even happen against your own will and better judgement. If you look at love through the filter of logic alone, it's not love. Love doesn't have to make sense beyond the sciences hidden in the background.

As a side note, by the logic of your first post, someone who finds other logical reasons to live would be incapable of love. Love would be the response only of those in existential crisis.

Love is an evolutionary social responce to the need to form pair bonds in order to reproduce, it is the emotional manifestation of oxytocin (the bonding hormone) which is released by most mammals to ensure pairs care for their offspring and defend against rival groups.

 I disagree. Love is a choice and a commitment. If you evaluate the quality and value of a relationship primarily in terms of your feelings, which can be fickle and fleeting, it is not likely to be successful over the long term.

All the same, you can have a relationship that has the choices and commitments made to be together, but not actually feel love within it.

Love is a force, while a relationship is a partnership. Both together is awesome, but you can have one without the other.

 Love is not passion. It is a choice.

If love was passion, what happens if you have a period where you're not feeling it for a bit? Does the love die? That's why most relationships and marriages fail: they expect love to be passion. Who is passionate 100% the time?

What is happening "against your will" is lust and infatuation. Which is the mechanism that may (or may not) bring you to love, and lasts approximately two years at most. It is a physical response. From there is it up to you to act in the name of love.

Passion may accompany love, but it is not love itself. Love is not a feeling. It is not desire. It is a choice and it is an action.

You may call it passion for life if you will (which is a choice), but it is not passion for another person.

Love, by nature, is intermittent. Humans long for continuity and play love when they don't have love.

That is how it works.
