As a widow I can relate to this from the other side. Personally, it’s only been 8 months for me and I’m not ready to jump back on the horse yet but know that I will. If you two are doing things then she past the initial grief and moving on. I will say that losing a partner is a lot different than a divorce, emotionally. You may have to deal with some of the “my late…” conversations at times but it’s not a comparison it’s just a window into their past life and feelings. We all carry that into relationships it’s just having a spouse pass away, carries a deeper wound. It’ll also give you some insight to her and what she may be feeling or wanting.
