Should we file joint or separate if i'm on disability but spouse is self-employed?

we've always filed married-jointly (no dependents). we both have had our own self-employement schedules & all was fine. then i had to go on disability. i kept my self-employment schedule last year (tho i didn't earn anything over the limit). this is is nothing tho, so was going to end my business. so i'm not sure if we need to change how we file because of this. spouse still working as freelancer. my only income is the disability check each month.
thanks for the assistance.
