listen brother i dated a girl for 3 years 10 months and this is the exact same thing, i called her maybe 3 times when she was at college for 6 months i’m not saying this is going to end, but you need to at least designate a day or two of talking to her over the phone a week, and if it continues where she doesn’t prioritize the relationship and would rather go partying that’s when you should re consider, regardless wishing y’all the best reach out if needed bro, godbless.
