I lost him, but he is still there

I love the fact that people assume if you or someone else loses their fiance or husband, that if you or someone else starts dating again, you're over them. I lost my fiance the love of my life, and everyone just is getting uptight that I am dating someone else. I still love Brett with my heart, but loving someone who is not here gets lonely. Brett can't have all of my heart anymore, but he is still there. I just wish- no, I don't wish that people had to actually know what I am going through.
