My ex added his ex on Facebook?

My boyfriend of one year broke up with me two days back. I always loved him and never did anything wrong. We almost never fought and I thought it was going great. Two days back he told me it was not working out. I got a little upset but I didn't beg or plead for him to take me back. Today I couldn't help myself so I checked his fb account and I saw that he had added his ex back. I feel so miserable and cheated. I don't know what to do... how to cope with this. I am going insane with pain. Please help
