<human>: Summarize the given text in a few sentences.

First off, we have (or had) a perfectly healthy relationship for whole year of school together, where we seen each other for almost absurd amounts of time each day, and slept together every night. We have been together for 6 months, but now, we live in different cities, approximately 5 hours away from each other.

We both have work, and other friends, yet recently in the past week, communication seems to have stopped.

- there have been less video chatting (she used to message me almost every single day to do so)

- less texting, affectionate messages, and interest (which was also something that happened literally all the time)

Now, it feels like we are drifting apart, and neither of us seem excited to talk or see each other anymore.

Any advice of what to do or say? I've asked if anything is wrong and she said there is nothing wrong, she's just working and usually is tired..
<bot>: Girlfriend used to go above and beyond in communicating with me, and not it's stopped. Unsure of what to do and its seriously hitting me hard :/
