Service Manager fired me?

Not sure if i’m fired or not since this manager is not the head manager.

Anyways some context, this manager has been making a lot of “jokes” about my future at this company coming to an end. So much so that it’s not funny and he’s the only one laughing at these “jokes” I’ve been planning on leaving since things haven’t been going so well and been caught up with school and another job but never really found myself putting the effort into doing so.

He sends me this text on my day off and honestly not sure if he can fire me. I’m going to take it as i am fired used this day apply for a part time job. Tomorrow i’m supposed to work but if i get a call about where i am do i go in or do i say “you fired me, why would i come in?”
