is it worth it to date an exchange student?

i recently began dating a norwegian student that is coming to my school for one year and i really like him. we get along very well, and he likes me as well. but he is leaving back to norway in 10 months, and so i am wondering if it is worth it to be with him now, because either we will have a really depressing breakup later or have a long-distance relationship where i could see him MAYBE once a year. or is it better to just never get involved with him since he is moving back? (i live in america)
