Relationship

My ex broke up with me a year ago tomorrow, I’ve been absolutely heart broken not myself depressed anxiety ridden . He was my blanket , he was my everything I still love the boy . Even after he left me I slept over I still had sex w him . Recently two weeks ago I started to move on , and he told me he loves and missed me and just last night he told me idk if this will work so I’m obviously upset , I started moving on with this kid Conor he knew about all of it so he’s not without knowing . So now I’m just confused and don’t know what I should do
