I don’t know what to do please help?

I (21f) lied twice about smoking pot to my boyfriend (25m) and I am not sure what’s gotten into me that I just keep falling back into my old habits. I stopped smoking for 2 years after continuously smoking for 3/4 years and he doesn’t like that I smoke and wanted me to quit. The first time I stopped was 3 months ago and I recently started up again because of family stress. He found out and was mad I didn’t immediately tell him about it. Now he doesn’t want to talk to me and it’s been 2 days. Everytime I talk to him he cuts me off and basically tells me I’m a horrible person and I know I am. I wish he understood me more. I know I did wrong and should have told him everything from the beginning I just didn’t want him to look down on me or be disappointed in me because of how highly I look up to him and wanted to protect him from my messed up life. Please give me any advice I feel lost and I don’t know what to do. I’m such a horrible human and if I could take everything back I’d give anything to.
