I hate "Just find the right girl bro" advice

As a 20 year old guy, I heard this sentence for countless times, and now it bothers me. When I tell people that maybe my problem is really short stature -for I'm 5'5 tall- people disagree with me, they say "Height doesn't matter that much bro", "It must be something else" they add. Yet I tell them that most of the girls rejected me because of my height, they pointed that out themselves. So they say "Oh, that means you couldn't find the right girl".

I don't know if you agree with me or not, but I believe there's no such thing as "the right girl" or "the right guy". I believe the appearance matters more than you think. I believe there's no way for a person to be loved because of their "personality". There's no way to fall in love without sexual desire.

What are your thoughts?
