There are so many activities you could do to make a distanced relationship work. Movie nights (Netflix Party is a fantastic option), game nights, making dinner together over video call are all lovely options. What I find to be a perfect option, if you are wanting to plan activities together, is a shared calendar. This way you both actively have something to look forward to all the time.
As the classic saying goes, communication is key. You both need to consistently check in on the other and see if there is anything that can be done to improve the relationship. Long distance relationships, especially in university, can be extra difficult because of the new and exciting life you are embarking on. You are already meeting so many new people, joining societies and settling into university life. It can all become overwhelming. All in all, your relationship should lift you up and encourage you in life, not weigh your university experience down.
That being said, long distance relationships at university absolutely have the potential to work out. You both are going to miss each other, but regularly setting up plans of spending time together and checking in on each other can truly help. I feel like you know deep down if the relationship is worth it. If this is the case, you should go for it and put everything you have into it (all while keeping a balance with other parts of your life). You never know what will happen in the future.
