ok, i will tell you a hypothetical story and you explain to me whats wrong in it:

Ok, so there is a guy, and he is in the club and he meets some females that he would like to fuck. Observing the quality of females, he asseses that, of the three, and on a scale of 1-5, they range: 2;3;5. He talks to them and they all have a good time like little social primates. Fast forward, they get each others facebook, but the guy doesnt try to hit on the superior girls, but the one he thinks will most likely give sex. Now you think that this doesnt count because he is only after sex. Well, courting begins. He tells her what he likes and hates, and, circumstantionally, she is all that he hates about people (anti intelectual yolo mainstream party gurl), but they both agree that she is totally different than her girlfriends. Doesnt the guy kinda delude himself? Well, after some time spent courting, he totally starts fantasizing about marriage and kids with that, really sub-par being. A third person, would wonder what the fuck happened. Love ex nihilo? To the point of severely crippling himself and his future? Now you can say that im having presumptions, but lets say that 70% that there would be divorce due to incompatibility, that the child would be ugly, and that the guy would have to pay them huge sums of resources because herp derp. Is it ok for him to suffer just because the brain wants him to reproduce? But now oyu say, he wont suffer, he will feel very kimochi about it. But again, to a third observer, that is also a dog xD, it will be an illogical decision.

And now i need to mention a "pure" reasonto do things, that is objective. People just say that all feelings stem from evolutionary stuff and all of them are "false" by my standards. Even if that were true, we can at least look at the gravity of decisions made, some looking like illogical choices to the third person, and some being logical. Like i stated with the sugar cube. I dont get the feeling of love towards it as soon as i see it. I dont want to fuck it. I want it maybe to replenish some energy and feel good. A sugar cube wont set my life for the next 40 years. And the good feeling i get out of it want be so delusional, ex nihilo, and illogical like "loving" someone. People keep telling me that drugs are bad. Love is a drug. It makes you do illogical things and destroys your life. What if humans were like spiders and the female ate the male after sex? What would peple say then? That the male isnt being manipulated by his hardwired brain into making a very bad choice. "but it will make him happy, knowing that his offsprings will live because of him". Bullshit. Its clearly a bad choice, and i think we can agree on that.
