Have you guys ever went through a LDR before?

My last relationship is a 1500km distance one. At first we both believe we can work it through, and she also reassure me it's worth it(my first relationship, but not for her), but whoop, in the end a tons of problem surfaced and it just doesn't work, so she breakup with me. That actually sour the whole relationship thing for me and i find myself having worsening trust issue since then.

Will i do it again? Yeah! ᕕ( ᐛ )ᕗ (but actually idk but maybe still yes lol)
