Do you guys have those teachers who really make an impact?

:( well I do, and TODAY he told us next week will be his last week until he's moving to another state to live with his girlfriend. I'm really happy for him no he said he plans on proposing and starting a family with her but he's my favorite teacher and I had planned to have him all 4 years of HS, everyone in my class was crying today when he told us and idk how to feel better.. Please help.
