I need advice!

Right so yesterday I told my mum I was moving out with my boyfriend and she went mental and got my whole family to basically shout at me, so yesterday being very emotional I argued with my boyfriend and told my family I broke up with him and they were all over joyed, but me and him talked and were fine now but can't tell anyone. What will I do? I want to be with him but my family hate him!😭
Just to add, I am 18. They hate him because he doesn't have a job because he has bad back problems but they don't understand that!
