Consistent goodbyes and obstacles

I'm feeling frustrated and hopeless. Each time I finally find a guy I click with, I open myself up to them, an obstacle appears, and the obstacle is usually them moving interstate or countries. Recently, I fell head over heels for a guy, who ticks all of my boxes and is one of the most kind hearted people I've ever been with, and he tells me he's moving to the other side of the world for work. In the middle of a global pandemic. The two guys before him both moved interstate for their careers. I'm so sick of opening myself up to someone who's just going to leave me. I know it's nothing personal, but that's almost worse. If it were personal, I could do something about it. Instead, I'm encountering constant obstacles in my love life, and losing hope each time. It hasn't gotten easier to say goodbye.
