I Have An Ex Boyfriend Who Is Still In Love With Me

My ex boyfriend decided to travel long way to see me as a surprise so he insists on saying . We got in touch after one year due to the corona virus as he said he was worried about me and thinking of me. Two weeks into chatting ( every other day) bam...he is here and in isolation (14 days by law) so far it's been 4 days, I haven't seen him. I don't want to see him as I know what's gonna happen. But he came a such long way.. I just know that when I see him especially now we will get back together but I am enjoying my freedom. What do I do? It's stressing me out😔 I don't have the heart to say turn back, go away, but I really wish he didn't come. I dont want to see him in person and of course he wants to live with me after his isolation...what do I do? What do I say to him? Or should I just see him and see how it goes .
