Do I move to Europe for him

I just returned after 3 months in Europe with my fiancé. I’m heartbroken. I can’t sleep, I can’t eat, and I feel displaced. We have been in a long distance relationship for 4 years. He can’t come to America right now. I have a masters program coming up but don’t know if I want to do it because I could be with him and look for a job there, never mind save me 70k in student loans. Help me 😔 I need opinions. I just want to start our life together after all of our suffering
