As you were already advised in your other thread, you need to focus on proving your ties to your country of residence.
I applied two weeks for trv to visit my fiance and got rejected .. I want tl reapply. We met online in 2014 then six months later he came to see me, then again and again. Three times . So this summer, I have break from uni so I really wanted to see him for few weeks. In the application I did not wrote any letter about us . I just said want to visit fiance. And I gave many photos of us and he and my family and some master thesis extract where he dedicate a part of acknowledgment to me. I dont know If I should provide more proof of relationship now as hotel we booked when he came here, or tell our story how we met.. I don't know
