LDR do I end it?

I met my girlfriend in college and we started a relationship 4 to 5 months before her going back home after graduating, I went to her graduation and met her whole family despite some being prejudice. She’s doing a gap year trying to get law school admissions and saving money together and I’m here at home doing nursing and pre med. She left in May and up until about a week ago the communication has been mutually good. I try to send her things like letters and little things and of course something for her birthday recently (she even wants to get me things but ofc I make more so I can help do more) and try to update and communicate when I have my 4 days off. Recently for about a week or two I’ve been more initiating conversations, calling when I can, trying to ask if I did something to offend her and she attributes it to working at a high volume. She lifeguards and can’t have her phone on the stand 5 days a week and sometimes does night swim and works at her aunts law firm for another day (six days of working) and still has to study for the LSAT and do law school processes so I get it but if this is LDR maybe an update or something would be nice. Sometimes I might get a picture when she’s with her friends or at the gym or she will wish me goodnight and we will talk about her day. Should I be more anal about what’s going on or understanding
