The love of my life passed away less than 5 weeks ago. Prior to being diagnosed with cancer, we had been on and off for about 7 months because he had to move. We had been together 5 and a half years prior to that. When he got sick, I started taking care of him and he passed away 7 months later. I found out yesterday that during that period where we were on and off, he had dated someone for about 3 months. She turned out to be nice enough to answer my questions, saying it wasn’t that serious but that she had been there when the doctor first diagnosed him and that at that point they were devastated and said I love you to each other. I am devastated by this news and wonder if any of it was real. She told me that he ended it and cut things off with her (around the time that I came back full time into his life). But I do know now that he had texted her a couple of times after that and saw her at least one more time. Am I foolish for thinking that he loved me?
