I lied to my boyfriend about not having a previous boyfriend, will he forgive me or dump me?

I wasn’t honest becuase I didn’t want to speak about my ex, I don’t care about him and just wanna focus on the present. He’s really upset that I didn’t tell him. I wanna make it up to him but understand if he wants to dump me for it
