I think I’m doomed to be alone

Was dating a guy in 2017 but he had to move abroad for work, I was gutted

Met a guy friend and really liked him, then he moved away across the country

Then I moved into a house share and made friends with a lovely guy, he announced he really liked me but was moving to Australia

I met a guy last November and we’ve been inseparable since. I was starting to get strong feelings and now he’s announced he’s moving across the country 4 hours away. I’m gutted

Why does this always happen to me with every single guy I’ve ever liked, I’m soooo worrried single forever
