Is it okay to get ghosted?

Okay so I've been talking to this girl since January. I met her online on December we hit off great but suddenly her best friend passed away so she needed time. So we didn't talk for like a month. We reconnected recently and things have been pretty great but the thing is she's from different state it's long distance. We talk on call and send voice noted, everything's good. But her thing is she randomly keeps me on delivered for full day although she gives a valid reason. I got left on delivered today too and I know she'll reply me tomorrow saying why she wasn't online. The things is I believe you can message anyone taking out atleast a minute out of you work and text you won't be busy. I don't know anymore what to do. Some advice would be really helpful and yeah sorry for bad english.
