Custom login page always redirecting to wp-login.php

Question

I've created a custom login page where users can login on my website, but when I try to log in, it's redirected to wp-login.php and I have to enter a reCAPTCHA (I hate those!).

I've already tried to redict wp-login.php to my custom login page, which works, but the outcome is that now I'm in an infinite loop of redirecting to the same custom login page and not being able to actually log in.

How can I do this?

EDIT

My custom login page looks exactly like this:

<?php get_header(); ?>
<div class="container">
<div class="row" style="margin:1em 0;">
    <div class="col-12 login-page">
        <h1>Inloggen</h1>
        <?php
        if ( ! is_user_logged_in() ) {
            $args = array(
                'redirect' => home_url(), 
                'form_id' => 'main-login',
                'label_username' => 'Gebruikersnaam',
                'label_password' => 'Wachtwoord',
                'label_remember' => 'Onthoud mij',
                'label_log_in' => 'Inloggen',
                'value_remember' => true,
                'remember' => true
            );
            wp_login_form( $args );
        } else {
            echo '<p style="text-align:center">' . wp_get_current_user()->user_firstname . '? Je bent al ingelogd. Ga maar wat Netflixen!</p><p style="text-align:center">Wil je uitloggen? Dat kan door <a href="https://www.telecinegids.be/wp-login.php?action=logout&redirect_to=https%3A%2F%2Fwww.myurl.be&_wpnonce=nonce">hier</a> te klikken.</p>';
        }
        ?>
    </div>
</div>
</div>
<?php get_footer();

It's all well and good to build a login page, but you need some way to tell WP to actually use your custom page.

Luckily, there is a way to do that, with a filter (of course):

add_action('init','redirect_login_page');
function redirect_login_page() {
  // your login page code
}

Put your code (or call a template) inside the function. And place the above code in your functions.php (in your Child Theme, hopefully, since you don't want a theme update to overwrite your custom code on a theme update).

More details are available here https://premium.wpmudev.org/blog/customize-login-page/ and in the Codex https://codex.wordpress.org/Function_Reference/wp_login_form, plus lots of other resources about customizing the login page on the googles.
