My dad died almost 2 months ago and my brother and sister in law haven't reached out to me. They have posted in our family group chat to say that they are thinking about us and then immediately moved on to talk about their own happy news. They haven't said anything directly to me and whenever it comes up they just talk about something else going on in their lives. I feel really sad and angry about it, and I can't believe that they didn't reach out, especially my sister in law. They are not the easiest but they preach about how much they love family all the time, and at this super important time they didn't show up for me or for my partner, who was also really close to my dad. I don't want to dwell on it or create any family drama but I feel like I don't want to see them or make any effort with them anymore. My partner understands and has listened but also thinks that I should just let it go and give them the benefit of the doubt. I don't know if I'm over reacting and should just let it go but it feels too important to do that.
