What do you do when you lose the One?

So I've just been dumped by my boyfriend. From the moment I met him something just clicked and I knew he was the person I'm meant to be with. We had this incredible connection, got along like best friends and had the most incredible mind blowing sex that always felt like making love, even from the first time. I'm 26 and have had plenty of boyfriends before, but they had nothing on him. Everything in me knows he's my person.
