I started flirting again with my childhood sweetheart who I thought was single. We got to sexting and then later agreed to have sex. I found out after that he had someone. He said he didnt mind continuing what we had if I chose to. I was so lonely that I continued it even if I knew it was wrong, only for him to vanish a few weeks later. I was so heartbroken. My confession: I would'nt mind doing it all over again.
