It is not clear from your post whether you are in fact a tenant, or if you were an occupant of premises that were rented by your boyfriend. If you were a tenant, you should be named as a party to the eviction lawsuit. If you were not a tenant, the eviction of your boyfriend as the sole actual tenant would carry over to you as an occupant of his rental unit. Without knowing additional facts, we're not in a position to comment.
If you're truly not sure whether the landlord intends to evict you, speak to the landlord. If you intend to move but need some additional time to find alternative housing, discuss the possibility with the landlord about your staying until (but no longer than) an agreed date and surrendering the unit on that date.
