My husband’s entire family live away from us, including his sibling in New Zealand (he only has one sibling). She is terrible at keeping in contact, despite our best efforts over the years. She now has children we have never met, which I know my husband feels horrible about. We were due to see them last year but of course couldn’t. His parents feel her absence very much, and even though they don’t see us much either they don’t seem to miss us as much as her.
My older kids know who she is and have spent time with her over the years, however my youngest has no idea who she is at all. She makes time to FaceTime her parents a few times a week, but rarely responds to my husband’s requests to FaceTime with her, so the kids never get to see her even on there.
Probably different as it’s not my sibling (I’d be gutted if one of mine left, not that they ever would!) but I do feel she makes no effort to stay in touch so we (the kids and I) kind of just forget about her as she obviously isn’t interested in being part of their lives.
