Pregnant after plan b

After accidently slipping up during intercourse I took a plan b 2 days later and missed me period this month other times I’ve taken it it’s never failed me but I found out I was pregnant this week and im so scared he said he never wants kids and we are just sleeping together no relationships don’t know what to say or how to tell him any advice ? And even tho we sleep together we are just keeping it has “friends “ nothing more so Idk how he’ll take it I’m honestly scared he’ll never even talk to me again he’s going on vacation this week I’m gonna tell him when he gets back
