My (24F) boyfriend (24M) going abroad for grad school

I’m feeling very conflicted right now, though this is a scenario that has played out in my head many times, finally becoming real. My boyfriend just got accepted to grad school (hasn’t said yes yet) and would be going for International Studies, which includes study abroad opportunities.

I just really need some positive experiences of people who have been through an extended period of their partner studying abroad. I am very happy for him and I really want him to pursue this, but I’m scared that I won’t be strong enough.

For context, we’ve been together for almost 3 years and been medium (3 hr) distance for about a year and a half. How did you manage to cope with your partner being away for so long? How did you avoid jealousy and what were some ways that helped you cope? How are you and your partner afterwards?

My best friend has been abroad before, and she lives far away for grad school now, and we have a great relationship. But I don’t miss her like I do my boyfriend of course. So I’m confident that I’d be able to maintain a relationship but just worried about that whole sense of dread with him being across the globe…
