People can try as hard as they may, but evolution says the FIRST REASON people are attracted to one another is because physically, they think they would make an good mate to produce strong children with. THIS IS THE EVOLUTIONARY TRUTH, in accordance to heterosexual couples. This obviously doesn't account for heterosexual couples. This being said, there are always exceptions. Also, we decide what happens once we are attracted to or not attracted to a person. They could be incredibly good looking but a complete dud, and that ends that attraction. Or the opposite, they could be "average" looking but after getting to know them, you fall in love with their personality and then everything about them becomes attractive. This also has an evolutionary standpoint, because humans seek what is familiar in themselves sin other people when seeing a mate under most circumstances, because that is what you subconsciously want to procreate. I actually have a pretty weird story in accordance to your question. I met my current boyfriend on an app called Tinder. His pictures were absolutely adorable. He looked maybe a liiittle chunky, but I loved his eyes and his hair, and he had a great smile. PLUS, he loves cats, Harry Potter and Tool. He was a BARTENDER at my favorite club, for goodness' sake! We texted for three days straight and I told my mom I was going to marry him before I even met him in person. But, when I did meet him in person, it turned out we were the same height -- 5'4. He was a shortie...and I was instantly turned off and friendzoned him. I didn't want to date a short, stocky guy. Well, he pursued me pretty hard, and I finally gave him a real chance, and I ended up falling in love with him, and now I think he's God's sexiest creation ad my mom also thinks I'm going to marry him. So, there's all that. Take of it what you will, just remember genetics and evolution dominates all things subconsciously, but we decide what happens after according to our personal values.
