Page continues redirecting to mobile site.

Question

I have my website www.jorgeromero.me (I'm still a beginer so please give me opinios on what to improve, thanks)
I have designed a mobile view of my regular site and in the head of the Desktop View site  I placed the following Java Script to redirect to mobile site to devices less than 800 px:
<script type="text/javascript">
<!--
if (screen.width <= 800) {
window.location = "http://www.jorgeromero.me/welcome-to-my-page-mobile/";
//-->
</script>
It works very well in mobile devices, the only thing I've noticed is that when I click "desktop view" to go to the regular site, it will keep redirecting me to the mobile site which makes sense because Java Script is doing what it's been asked for.
I tried placing this code in the head of the mobile site to redirect to the desktop view but it only makes a loop in the browser which also makes sense
<script type="text/javascript">
<!--
if (screen.width >= 800) {
window.location = "http://www.jorgeromero.me";
//-->
</script>
My question is.... what could I do in order to still be able to visit the desktop site when I click "desktop view" in the mobile site.
Thanks a lot in advance for your help!!
