Breaking up with a soulmate

My boyfriend recently broke up with me for the 2nd time over one issue. We had a complicated history with him, being best friends for three years and me dating his friend for those years. At some point last year I broke up with his friend because we didnt click and ended up falling for him and after 2-3 weeks of thinking if it is a good idea, we started getting into it. But then I relapsed because of all my money and documents were stolen (I live away from him and home, in another country). My ex found out about it and came to support me and we ended up sleeping with each other. We didnt tell our friend since that day he also decided somehow that we wont work and everything went back to normal, I got back together with my ex for a little while but it didnt work out. Then after a while I decided to tell my friend what really happened that day and he was furious for a while but ended up telling me he forgave me few months later. Then we got together but he broke it off after a few days saying he actually hasnt forgiven me. A month later he texted me again and we started talking and then when I visited home we did get together and had amazing time and kept it on for a while when I left. Then few days ago out of the blue he told me that his family and friends are against me because of that thing and broke it off again. Sorry for the long story, must also sounds very dramatic. Now I feel like I lost "the one" cause we clicked together so well, almost finishing each sentenses
