Help with code to prevent Nav jumping to second line / collapsing onto logo

I recently found some coding to split our navigation on either side of the logo - however, whenever the site is displayed on a smaller computer now or a smaller window - the navigation collapses too close to the logo, and also carries over to the second line. Is there any way to make this so the navigation spacing is reduced or the edge limits as to how wide the navigation can go before jumping to a second line can be widened? Any help would be greatly appreciated! Attaching photo's of the issue. Thank you!

Here's the current code i was using

/*Make split navigation*/
.header-nav {
    position: absolute;
    top: 60px;
    bottom: 0;
    margin-top: 1!important;
    margin-left: 0px!important;
}

.header-nav-item:nth-of-type(3) {
    margin-right: 440px!important;
}

.header-title-logo a {
    z-index: 1000;
    position: relative;
}

/* remove page width limit */
#page .content-wrapper {
    max-width: 100% !important;
}

Just solved a similar question. If you change Header Layout to Left Nav - Middle Logo then share url, we can give another code to achieve split layout.
