DP was pretty awkward when my grandmother died just before Christmas. He was sympathetic and available on the surface, but was clearly uncomfortable with me talking about it, uncomfortable that I was really upset, and just didn't know what to do or say. He was also quite blasé about it, didn't ask me about it again, or how I was after a day or two after she died and didn't really offer to do anything nice or thoughtful for me. I was a bit disappointed in his response tbh. He has lost grandparents and other relatives so it's not like he hasn't experienced this himself. He's also usually quite mature about difficult situations so I was surprised.
Unfortunately my grandfather has now just passed away too. DP has had the same response and it's made me now not want to talk to him or involve him in my latest loss at all. I honestly just can't face talking to him. He hasn't tried to call me or anything since it happened anyway, just sent me a couple of messages. Do you think I should tell him how I feel? And if so, what do I say?
