How long should our break be ? & advice ??

I’m going through stuff mentally and emotionally one day I’m happy and then the next 2 I’m sad and I just don’t know why so I just been dry texting my bf and I feel like he has a lot on his plate so I didn’t tell him my problems I was just dry texting him and he said he feels like I don’t wanna be with him so I told him everything and he said let’s just take a break and I agreed on it bc I do need a break from everything right now and he said it’s the best thing to do rn until we get our selfs together so how long should our break be ?

EDIT: WE BOTH ARE GOING THROUGH ALOT AND WE NEED A BREAK FROM EACH OTHER AND MOSTLY EVERYONE ELSE💯.
