Almost 3 years ago my sister and BIL split up - together 11 years in total, married for only 2. Long story short but he discovered she had been having an affair. They have now both moved on with their lives. BIL stayed in touch with me, DP and DD for about 12 months or so before he slowly started to respond less to messages etc. Contact is very minimal now - DD will occasionally say he's messaged her to see how she is. DD is a teen now and was 2 years old when they first met - he was so good with her and an important male figure in her life - she still refers to him as "Uncle Jack" (not his real name).
I still have him on my friends list on FB and when I see his updates with his new partner (who he looks very happy with), I can't help but feel a pang of sadness as I just really miss him being a part of our family. It's been 3 years but I still feel that sadness at times. It might be because I had a baby recently and I wish he was a part of my new baby's life too, as he was so good with my eldest.
Part of me still feels annoyed at my sister as I see her as responsible for him not being in our lives anymore. But I know I need to get over that. Anyway I'm not sure what I want from this post. Just wondering if anyone has been through similar, ie losing an extended family member due to relationship breakdown. And do you think I'm being unreasonable for missing him still 3 years on? Tbh, he was honestly more like a brother to me than a BIL. I suppose that's why it's so hard
