Seriously Heartbroken

Me and my s/o of about a year and a half just broke up. It doesn’t even feel real, but at the same time it felt inevitable. I posted earlier asking advice on some issues we’ve been having and most everyone said it sounds like it needs to end. Well, as much as I didn’t want to believe it, it actually had to end. I’ve never been heartbroken like this before, it’s like I just lost my whole life. He’s my best friend, my world has revolved around him for so long. I’ve never gone through this before and I feel so broken ): Will I ever be over it completely? The issues I confronted him about to day have been happening time and time again and it all comes down to him not communicating. He said he thinks he needs to be single for a little while and that I deserve better. Can’t really imagine anyone better than him.
