Girl's Behavior

Friend left my message on Snapchat on delivered for 5 days. Should I cut her off?

So my friend who I’ve known for 10 years and i recently started talking again on Snapchat. I noticed that this time she hasn’t opened my message in 5 days. What possible reason does she have for this? As a long time friend I feel it’s kind of disrespectful and she’s done it before for 7 days (even posting on Snapchat and deleting it because she knew she didn’t open my message) should I cut it off for good? We’ve had no reason to fall out whatsoever.
