Highlight the Selected Menu Item with one href ="/"

Highlight the Selected Menu Item with one href ="/"

I am seeking help in resolve the following problem. 

I have created a menu and use JQuery to highlight the selected menu item (WordPress site). But one of the href used has to be "/" for home page. When selecting any other menu item the item for the home page is always highlighted.

The following are the codes:

HTML
<style>
.active {
    color: red;
    font-weight:600;
}
</style>

<div id="custom-menu" class="custom-menu col-full" style="border:0px solid red;">
        <ul>
                <li><a id="main" class="btn" href="/">Home Page</a></li>
                <li><a class="btn" href="/perform/">Perform</a></li>
                <li><a class="btn" href="/museum/">Museum</a></li>
                <li><a class="btn" href="/hangout/">Hangout</a></li>
                <li><a class="btn" href="/markets/">Markets</a></li>
                <li><a class="btn" href="/my-events/">My Events</a></li>
                <li><a class="btn" href="/events/list/">Search</a></li>
        </ul>
</div>


jQuery Code
//User jQuery instead of "$" in WordPress to avoid code conflict 

jQuery(document).ready(function(){

  jQuery(".custom-menu a").each(function() {
     //console.log(jQuery(this).attr('href'));
     if ((window.location.pathname.indexOf(jQuery(this).attr('href'))) > -1) {
        jQuery(this).addClass('active');
     }
  });
});

I would be grateful if anyone could help me resolve this quickly!
