I don't understand? How can u love someone day and the next they don't even want to know u. Ghosted? mme?

I been with this bloke for a year now. We travel up to cairns together took us 2 months to get there. I then fly back home to sort my daughter out why he stayed there. We talked every day. 2 months later was meant to fly back up there. He watch me pack my bags on video call.16 days before leaving on Christmas day he sent a text sayin he sleep with someone else. And i need to fix myself up.. And nothing since. He has ghosted me since.. Knowing that my ticket was no refund. So lost 450. I was about to up my hole life for this bloke.. And he doesn't even care. He got me block. I can't get my head around it all.. I dont understand.. Why? Has he done this? Im more upset about losing our friendship? So was the last year just a big lie... ? It eatin at me.. I can't get it out of my head. I need help to understand why? l

I don't understand how we where so close and now I can't even get him to answer. I'm more piss cause I thought we had a really good friendship. And I'm not the one that said I love you first it was him. This is really gettin to me.. Everyone say get over it. And I will in time but I was going to up my whole life..
