My friend deleted me off Snapchat because I couldn’t go clubbing? We are 21 years old?

Shall I react to this? I told her I might be able to go Saturday but things came up as I got a new job ( which she dosent care about at all or take into consideration or say congrats ) she just got salty about it saying why did you tell me you were free. I didn’t know I got the job then? So she said maybe today and I said I’m going away today but I’m not sure if I’m going yet I will let you know. She just ignored me and deleted me off Snapchat? Shall I just leave it and not say a word? Is it worth it? She’s been going through a bad time with her boyfriend but why take it out on me and delete me for not going out!
