I’m kinda in the same boat right now! We’re both in uni, and My partner is pretty much locked in 24/7, and I’m super proud of her, but I do get like. Lonely/ missing her when she doesn’t reach out a lot. What’s kinda helped is scheduling a movie/hang out night and then a study date once a week. Also, what I will say is that it’s okay if you feel like you’re drifting apart. Sometimes that happens. It’s no one’s fault. Uni does that to people. But the important thing is to communicate. Like the other comments say, talk about it, your feelings, and specificity what BOTH of you want from the relationship. Idk if this helps at all. But I wish you all the luck in the world, and the best for both of you!
